Add current WIP on complex text rendering; misc. changes
Note: the text rendering is in a very early stage - I didn't even bother to add delete functions for anything yet.
The current up-to-date file for the text rendering engine is text-hb.ubernew.c.
/me shall now go on hiatus for a while in order to learn a lot about Xlib and other things so he can come back and actually have a clue what he's doing.

+// faster and generally-more-precise rasterizer. The new rasterizer more
+// accurately measures pixel coverage for anti-aliasing, except in the case
+// where multiple shapes overlap, in which case it overestimates the AA pixel
+// coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
+// this turns out to be a problem, you can re-enable the old rasterizer with
+// #define STBTT_RASTERIZER_VERSION 1
+// which will incur about a 15% speed hit.
+//
+// ADDITIONAL DOCUMENTATION
+//
+// Immediately after this block comment are a series of sample programs.
+//
+// After the sample programs is the "header file" section. This section
+// includes documentation for each API function.
+//
+// Some important concepts to understand to use this library:
+//
+// Codepoint
+// Characters are defined by unicode codepoints, e.g. 65 is
+// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
+// the hiragana for "ma".
+//
+// Glyph
+// A visual character shape (every codepoint is rendered as
+// some glyph)
+//
+// Glyph index
+// A font-specific integer ID representing a glyph
+//
+// Baseline
+// Glyph shapes are defined relative to a baseline, which is the
+// bottom of uppercase characters. Characters extend both above
+// and below the baseline.
+//
+// Current Point
+// As you draw text to the screen, you keep track of a "current point"
+// which is the origin of each character. The current point's vertical
+// position is the baseline. Even "baked fonts" use this model.
+//
+// Vertical Font Metrics
+// The vertical qualities of the font, used to vertically position
+// and space the characters. See docs for stbtt_GetFontVMetrics.
+//
+// Font Size in Pixels or Points
+// The preferred interface for specifying font sizes in stb_truetype
+// is to specify how tall the font's vertical extent should be in pixels.
+// If that sounds good enough, skip the next paragraph.
+//
+// Most font APIs instead use "points", which are a common typographic
+// measurement for describing font size, defined as 72 points per inch.
+// stb_truetype provides a point API for compatibility. However, true
+// "per inch" conventions don't make much sense on computer displays
+// since they different monitors have different number of pixels per
+// inch. For example, Windows traditionally uses a convention that
+// there are 96 pixels per inch, thus making 'inch' measurements have
+// nothing to do with inches, and thus effectively defining a point to
+// be 1.333 pixels. Additionally, the TrueType font data provides
+// an explicit scale factor to scale a given font's glyphs to points,
+// but the author has observed that this scale factor is often wrong
+// for non-commercial fonts, thus making fonts scaled in points
+// according to the TrueType spec incoherently sized in practice.
+//
+// ADVANCED USAGE
+//
+// Quality:
+//
+// - Use the functions with Subpixel at the end to allow your characters
+// to have subpixel positioning. Since the font is anti-aliased, not
+// hinted, this is very import for quality. (This is not possible with
+// baked fonts.)
+//
+// - Kerning is now supported, and if you're supporting subpixel rendering
+// then kerning is worth using to give your text a polished look.
+//
+// Performance:
+//
+// - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
+// if you don't do this, stb_truetype is forced to do the conversion on
+// every call.
+//
+// - There are a lot of memory allocations. We should modify it to take
+// a temp buffer and allocate from the temp buffer (without freeing),
+// should help performance a lot.
+//
+// NOTES
+//
+// The system uses the raw data found in the .ttf file without changing it
+// and without building auxiliary data structures. This is a bit inefficient
+// on little-endian systems (the data is big-endian), but assuming you're
+// caching the bitmaps or glyph shapes this shouldn't be a big deal.
+//
+// It appears to be very hard to programmatically determine what font a
+// given file is in a general way. I provide an API for this, but I don't
+// recommend it.

+FONTLOG
+Gentium Plus font family
+========================
+
+
+This file provides detailed information on the Gentium Plus family of fonts.
+This information should be distributed along with the Gentium Plus fonts and
+any derivative works.
+
+
+Basic Font Information
+----------------------
+
+Gentium ("belonging to the nations" in Latin) is a Unicode typeface family
+designed to enable the many diverse ethnic groups around the world who use
+the Latin script to produce readable, high-quality publications. The
+design is intended to be highly readable, reasonably compact, and visually
+attractive. Gentium has won a "Certificate of Excellence in Typeface
+Design" in two major international typeface design competitions:
+bukva:raz! (2001), TDC2003 (2003).
+
+The Gentium Plus font family is based on the original design. It currently
+comes with regular and italic face only, although additional weights are in
+development.
+
+The goal for this product is to provide a single Unicode-based font family
+that contains a comprehensive inventory of glyphs needed for almost any
+Roman- or Cyrillic-based writing system, whether used for phonetic or
+orthographic needs, and provide a matching Greek face. In addition, there
+is provision for other characters and symbols useful to linguists. This
+font makes use of state-of-the-art font technologies to support complex
+typographic issues, such as the need to position arbitrary combinations
+of base glyphs and diacritics optimally.
+
+Two fonts from this typeface family are included in this release:
+
+ * Gentium Plus Regular
+ * Gentium Plus Italic
+
+Work is ongoing to provide bold and bold-italic weights, as well as a
+complete book-weight family.
+
+For detailed documentation see the contents of the 'documentation' folder.
+
+
+A Note Regarding the Open Font License and TypeTuner
+----------------------------------------------------
+
+The OFL prohibits the use of Reserved Font Names "Gentium" and "SIL" in
+the name of any font that is derived from the Original Version of Gentium
+Plus. However, SIL International (the Copyright Holder) grants through
+this separate written agreement the right to use the Reserved Font Names
+in any Modified Version of this font created by using TypeTuner as long
+as the feature information contained in the Original Version is used,
+unmodified, as the source for TypeTuner feature information, and
+"Gentium Plus" is not the resulting font family name.
+
+TypeTuner-produced fonts created in this manner are still bound by the
+terms of the OFL. Specifically, the use of Reserved Font Names is
+prohibited when making derivatives of a TypeTuner-produced font. Anyone
+making a derivative of a TypeTuner font will need to find a different
+name. For example a TypeTuner-produced font may be named
+"Gentium Plus Literacy SomeFarAwayPlace" but a derivative of that font made
+with other tools would not be allowed to use the "Gentium" and "SIL"
+Reserved Font Names and would have to be named something like "Nations Serif".
+

+
+Information for Developers/Contributors
+---------------------------------------
+
+The release of Gentium Plus version 1.502 (and any subsequent versions) under
+the OFL license provides a means for people to modify the fonts to meet their
+needs and contribute to the project. For information on what you're allowed to
+change or modify, consult the OFL and OFL-FAQ.
+
+Anyone can make their own modified version of Gentium Plus (using a different
+name), but SIL International will continue to maintain and develop the
+canonical version of the Gentium Plus fonts. As the package maintainer, we
+welcome contributions. Here are some things to keep in mind:
+
+Format: We are open to contributions in various formats, but if you want to
+maximise the chances of us including your work, please make it available to
+us (via email or a URL) as either a FontLab database (preferred) or a
+PostScript Type 1 (or OT-CFF) font.
+
+Source files: The primary source files for the fonts are the fonts themselves.
+They contain all the important data in the fonts and can be studied and
+modified using open font tools such as FontForge and TTX. The developer
+release contains additional source files that might be useful. See the file
+source/SOURCES.txt in that release archive for further information.
+
+Copyright attribution: If you submit something for inclusion in the main
+Gentium Plus fonts, we will ask you to affirm that it is your original work,
+and ask you to assign the copyright of your work to SIL International. This
+is to ensure that future releases can be made under improved versions of the
+OFL without needing to track you down for further permission. This follows
+the same principle used by the FSF. Keep in mind that we are a
+not-for-profit organization committed to free/libre and open source
+software, and that any contributions incorporated in the fonts will always
+be available under the OFL or a similar license.
+
+Quality: Because we want to be able to guarantee a high level of quality for
+the primary Gentium Plus fonts, we will review submissions carefully. Please
+don't be discouraged if we do not include a submission for this reason, or
+ask you to make specific revisions.
+
+Types of contributions: If you wish to make a contribution - a set of
+additional glyphs, scripts, code, etc. - please contact us before you do any
+work to see if it is a contribution we currently need. Every addition adds
+to the complexity of the project and needs to be carefully planned. This
+also avoids two people working on the same type of addition at the same time.
+
+Linux packages: Please contact the upstream maintainer of the various
+packages - nicolas_spalinger@sil.org - if you want to help package or
+maintain a package.
+
+When submissions will be included: We plan to revise the fonts when major
+updates are needed (eg new versions of Unicode). If you wish to make
+submissions, contact us on the timing.
+
+

+GENTIUM-FAQ
+Gentium Plus
+========================
+
+Here are some answers to frequently asked questions about the Gentium Plus
+fonts:
+
+
+General
+========
+
+How do you pronounce Gentium?
+
+ The preferred pronunciation is with a soft G as in 'general', not a
+ hard one as in 'gold': JEN-tee-oom.
+
+
+Licensing
+=========
+
+I want to use Gentium Plus in my publication - can I?
+
+ Gentium Plus is released under the SIL Open Font License, which permits
+ use for any publication, whether electronic or printed. For more answers
+ to use questions see the OFL-FAQ. The license, alongside information
+ specific to Gentium Plus, is in the release package.
+
+I would like to bundle Gentium Plus with my application - can I?
+
+ This is our most common question. The SIL Open Font License allows
+ bundling with applications, even commercial closed source ones, with
+ some restrictions. See the OFL.txt file and the OFL-FAQ.
+
+Can I use the font on my web site?
+
+ You can certainly create web pages that request that Gentium Plus be
+ used to display them (both if that font is already available on the
+ user's system or if it is delivered via @font-face). According to the
+ license, you are also allowed to place the font on your site for people
+ to download it. We would strongly recommend, however, that you direct
+ users to our site to download the font. This ensures that they are
+ always using the most recent version with bug fixes, etc. To make this
+ easier, there is a simple URL for Gentium: http://scripts.sil.org/Gentium
+ There is further important discussion of webfont issues in the OFL-FAQ.
+
+Is Gentium Plus going to stay unrestricted and available at no cost?
+
+ There is no intention to ever charge users for using Gentium and its
+ variants. The current version is licensed under a free/open license and
+ future versions will be similarly unencumbered.
+
+
+Modification
+============
+
+I would like to modify Gentium Plus to add a couple of characters I need.
+Can I?
+
+ Yes - that is allowed as long as you abide by the conditions of the
+ SIL Open Font License.
+
+So will you add glyphs upon request?
+
+ If you have a special symbol that you need (say, for a particular
+ transcription system), the best means of doing so will be to ensure
+ that the symbol makes it into the Unicode Standard. It is impossible
+ for us to add every glyph that every person desires, but we do place
+ a high priority on adding pretty much anything that falls in certain
+ Unicode ranges (extended Latin, Greek, Cyrillic). You can send us your
+ requests, but please understand that we are unlikely to add symbols
+ where the user base is very small, unless they have been accepted
+ into Unicode.
+
+Can I send you work I've done to be incorporated into Gentium Plus?
+
+ Yes. See the FONTLOG for information on becoming a contributor.
+
+
+Technical
+=========
+
+Can you help me get Gentium Plus working on my system?
+
+ We cannot afford to offer individual technical support. The best
+ resource is this website, where we hope to offer some limited help.
+ However, we do want to hear of any problems you encounter, so that
+ we can add them to the list of bugs to fix in later releases.
+ Our contact address is gentium@sil.org. Please understand
+ that we cannot guarantee a personal response.
+
+I can't find all the extended Latin letters in the font. How do I type them?
+
+ Gentium Plus is Unicode-encoded, which means that the computer stores a
+ special, unique code for each letter in your document. Since most
+ keyboards do not have hundreds of keys, special software is needed
+ in order to type the hundreds of special characters supported by the
+ font. See the README.txt file for more information.
+
+I can't find the 'o with right hook' in the font. Where is it?
+
+ Combinations of base letters with diacritics are often called
+ composite, or pre-composed glyphs. Gentium Plus has hundreds of these
+ (the ones that are included in Unicode). There are, however, many
+ common combinations that are not represented by a single composite.
+ It is possible to enter these into a document, but only as
+ individual components. So 'o with right hook' would be entered as
+ 'o', then 'right hook'. Although this may not look very good in some
+ cases, we're not able to anticipate every possible combination.
+ Gentium Plus includes 'smart font' support for both OpenType and
+ Graphite.
+
+Some diacritics are not aligning well with base glyphs, and if I type more
+than one diacritic, they run into each other. Why is that?
+
+ The smart diacritic positioning in Gentium Plus relies on either
+ OpenType or Graphite. The application you are using must support
+ one of these technologies in order to see appropriate diacritic
+ positioning.
+
+How do I type the Greek letters?
+
+ You need a Unicode-compatible keyboarding system, which is not
+ included in the release.
+
+I'm having problems making PDFs -- why won't my document distill?
+
+ Gentium Plus is a large font, with lots of glyphs. As a result,
+ some older printers, PDF distillers and readers can balk at PDFs
+ that have the complete font embedded. The easiest way to avoid
+ this is to have the PDF distiller subset the font. This is
+ generally a good idea anyway (with any font) and can reduce the
+ size of your files.
+
+
+Plus
+=====
+
+How are the Gentium Plus fonts different from Gentium?
+
+ This font is based on the original Gentium design, but with an expanded
+ character and glyph repertoire. It currently comes with regular and
+ italic faces. It comes with near-complete support for Latin, Cyrillic
+ and Greek. It also contains 'smart font' support for OpenType and Graphite
+ technologies. This allows for correct diacritic placement over all base
+ characters, whether they are tall, short, wide, narrow, with or without
+ descenders. It also provides for a large variety of alternates glyphs.
+ These are described on the Gentium website.
+
+Why is the line spacing greater for the Plus fonts?
+
+ In some environments, stacked diacritics in Gentium could display as
+ 'chopped-off'. Gentium Plus has slightly wider default line spacing
+ in order to avoid this problem. Most applications do, however, let you
+ set the line spacing explicitly, so you can have the lines spaced
+ precisely as you wish.
+
+Is there an Alt version of the Basic fonts?
+
+ No, although you may notice that capitals and some tall lowercase
+ letters do use 'low-profile' versions. Gentium Plus also includes
+ OpenType and Graphite features to turn low-profile diacritics on
+ and off.
+
+
+Future
+======
+
+What are your future plans for Gentium Plus?
+
+ Our next major effort is completing bold and bold italic weights
+ of Gentium Plus alongside a new Gentium Book Plus family. These new
+ weights are currently available for Gentium Basic/Gentium Book Basic.
+
+Do you plan to include other typographic enhancements (old style
+figures, etc.)?
+
+ Those would be nice, wouldn't they? From a design point of view,
+ it would be great to have these refinements, and we haven't ruled
+ them out. But there are other needs that are much higher priority
+ (such as bold). If you think you could contribute some of your time
+ and effort to these enhancements, see the FONTLOG.txt file for
+ information on becoming a contributor.
+
+Sans-serif?
+
+ There is a definite need for a sans-serif font that shares some of
+ Gentium's strengths -- high readability, economy of space, etc. It
+ would also be great if that font also harmonized well with Gentium.
+ We don't currently have any plans for a companion face, although one
+ of our other projects - Andika - may be useful. Andika is a sans-serif
+ font designed specifically for use in literacy programs around the
+ world, and is available from our web site.
+
+Will you be extending Gentium to cover other scripts, and Hebrew in
+particular?
+
+ It is very unlikely that we would do this, as there are so many
+ pressing needs in Latin, Greek and Cyrillic scripts.
+
+Will there be a Type 1 version? What about OpenType?
+
+ Gentium Plus includes OpenType and Graphite support. We do not plan
+ to produce Type 1 versions at this time, but please write us if this
+ is important (and tell us why). We already provide the PostScript
+ bézier curves in the 'designsource' files in the developer release.

+
+1 USING AND DISTRIBUTING FONTS LICENSED UNDER THE OFL
+
+1.1 Can I use the fonts for a book or other print publication, to create logos or other graphics or even to manufacture objects based on their outlines?
+Yes. You are very welcome to do so. Authors of fonts released under the OFL allow you to use their font software as such for any kind of design work. No additional license or permission is required, unlike with some other licenses. Some examples of these uses are: logos, posters, business cards, stationery, video titling, signage, t-shirts, personalised fabric, 3D-printed/laser-cut shapes, sculptures, rubber stamps, cookie cutters and lead type.
+
+1.1.1 Does that restrict the license or distribution of that artwork?
+No. You remain the author and copyright holder of that newly derived graphic or object. You are simply using an open font in the design process. It is only when you redistribute, bundle or modify the font itself that other conditions of the license have to be respected (see below for more details).
+
+1.1.2 Is any kind of acknowledgement required?
+No. Font authors may appreciate being mentioned in your artwork's acknowledgements alongside the name of the font, possibly with a link to their website, but that is not required.
+
+1.2 Can the fonts be included with Free/Libre and Open Source Software collections such as GNU/Linux and BSD distributions and repositories?
+Yes! Fonts licensed under the OFL can be freely included alongside other software under FLOSS (Free/Libre and Open Source Software) licenses. Since fonts are typically aggregated with, not merged into, existing software, there is little need to be concerned about incompatibility with existing software licenses. You may also repackage the fonts and the accompanying components in a .rpm or .deb package (or other similar package formats or installers) and include them in distribution CD/DVDs and online repositories. (Also see section 5.9 about rebuilding from source.)
+
+1.3 I want to distribute the fonts with my program. Does this mean my program also has to be Free/Libre and Open Source Software?
+No. Only the portions based on the Font Software are required to be released under the OFL. The intent of the license is to allow aggregation or bundling with software under restricted licensing as well.
+
+1.4 Can I sell a software package that includes these fonts?
+Yes, you can do this with both the Original Version and a Modified Version of the fonts. Examples of bundling made possible by the OFL would include: word processors, design and publishing applications, training and educational software, games and entertainment software, mobile device applications, etc.
+
+1.5 Can I include the fonts on a CD of freeware or commercial fonts?
+Yes, as long some other font or software is also on the disk, so the OFL font is not sold by itself.
+
+1.6 Why won't the OFL let me sell the fonts alone?
+The intent is to keep people from making money by simply redistributing the fonts. The only people who ought to profit directly from the fonts should be the original authors, and those authors have kindly given up potential direct income to distribute their fonts under the OFL. Please honour and respect their contribution!
+
+1.7 What about sharing OFL fonts with friends on a CD, DVD or USB stick?
+You are very welcome to share open fonts with friends, family and colleagues through removable media. Just remember to include the full font package, including any copyright notices and licensing information as available in OFL.txt. In the case where you sell the font, it has to come bundled with software.
+
+1.8 Can I host the fonts on a web site for others to use?
+Yes, as long as you make the full font package available. In most cases it may be best to point users to the main site that distributes the Original Version so they always get the most recent stable and complete version. See also discussion of web fonts in Section 2.
+
+1.9 Can I host the fonts on a server for use over our internal network?
+Yes. If the fonts are transferred from the server to the client computer by means that allow them to be used even if the computer is no longer attached to the network, the full package (copyright notices, licensing information, etc.) should be included.
+
+1.10 Does the full OFL license text always need to accompany the font?
+The only situation in which an OFL font can be distributed without the text of the OFL (either in a separate file or in font metadata), is when a font is embedded in a document or bundled within a program. In the case of metadata included within a font, it is legally sufficient to include only a link to the text of the OFL on http://scripts.sil.org/OFL, but we strongly recommend against this. Most modern font formats include metadata fields that will accept the full OFL text, and full inclusion increases the likelihood that users will understand and properly apply the license.
+
+1.11 What do you mean by 'embedding'? How does that differ from other means of distribution?
+By 'embedding' we mean inclusion of the font in a document or file in a way that makes extraction (and redistribution) difficult or clearly discouraged. In many cases the names of embedded fonts might also not be obvious to those reading the document, the font data format might be altered, and only a subset of the font - only the glyphs required for the text - might be included. Any other means of delivering a font to another person is considered 'distribution', and needs to be accompanied by any copyright notices and licensing information available in OFL.txt.
+
+1.12 So can I embed OFL fonts in my document?
+Yes, either in full or a subset. The restrictions regarding font modification and redistribution do not apply, as the font is not intended for use outside the document.
+
+1.13 Does embedding alter the license of the document itself?
+No. Referencing or embedding an OFL font in any document does not change the license of the document itself. The requirement for fonts to remain under the OFL does not apply to any document created using the fonts and their derivatives. Similarly, creating any kind of graphic using a font under OFL does not make the resulting artwork subject to the OFL.
+
+1.14 If OFL fonts are extracted from a document in which they are embedded (such as a PDF file), what can be done with them? Is this a risk to author(s)?
+The few utilities that can extract fonts embedded in a PDF will typically output limited amounts of outlines - not a complete font. To create a working font from this method is much more difficult and time consuming than finding the source of the original OFL font. So there is little chance that an OFL font would be extracted and redistributed inappropriately through this method. Even so, copyright laws address any misrepresentation of authorship. All Font Software released under the OFL and marked as such by the author(s) is intended to remain under this license regardless of the distribution method, and cannot be redistributed under any other license. We strongly discourage any font extraction - we recommend directly using the font sources instead - but if you extract font outlines from a document, please be considerate: respect the work of the author(s) and the licensing model.
+
+1.15 What about distributing fonts with a document? Within a compressed folder structure? Is it distribution, bundling or embedding?
+Certain document formats may allow the inclusion of an unmodified font within their file structure which may consist of a compressed folder containing the various resources forming the document (such as pictures and thumbnails). Including fonts within such a structure is understood as being different from embedding but rather similar to bundling (or mere aggregation) which the license explicitly allows. In this case the font is conveyed unchanged whereas embedding a font usually transforms it from the original format. The OFL does not allow anyone to extract the font from such a structure to then redistribute it under another license. The explicit permission to redistribute and embed does not cancel the requirement for the Font Software to remain under the license chosen by its author(s). Even if the font travels inside the document as one of its assets, it should not lose its authorship information and licensing.
+
+1.16 What about ebooks shipping with open fonts?
+The requirements differ depending on whether the fonts are linked, embedded or distributed (bundled or aggregated). Some ebook formats use web technologies to do font linking via @font-face, others are designed for font embedding, some use fonts distributed with the document or reading software, and a few rely solely on the fonts already present on the target system. The license requirements depend on the type of inclusion as discussed in 1.15.
+
+1.17 Can Font Software released under the OFL be subject to URL-based access restrictions methods or DRM (Digital Rights Management) mechanisms?
+Yes, but these issues are out-of-scope for the OFL. The license itself neither encourages their use nor prohibits them since such mechanisms are not implemented in the components of the Font Software but through external software. Such restrictions are put in place for many different purposes corresponding to various usage scenarios. One common example is to limit potentially dangerous cross-site scripting attacks. However, in the spirit of libre/open fonts and unrestricted writing systems, we strongly encourage open sharing and reuse of OFL fonts, and the establishment of an environment where such restrictions are unnecessary. Note that whether you wish to use such mechanisms or you prefer not to, you must still abide by the rules set forth by the OFL when using fonts released by their authors under this license. Derivative fonts must be licensed under the OFL, even if they are part of a service for which you charge fees and/or for which access to source code is restricted. You may not sell the fonts on their own - they must be part of a larger software package, bundle or subscription plan. For example, even if the OFL font is distributed in a software package or via an online service using a DRM mechanism, the user would still have the right to extract that font, use, study, modify and redistribute it under the OFL.
+
+1.18 I've come across a font released under the OFL. How can I easily get more information about the Original Version? How can I know where it stands compared to the Original Version or other Modified Versions?
+Consult the copyright statement(s) in the license for ways to contact the original authors. Consult the FONTLOG (see section 6 for more details and examples) for information on how the font differs from the Original Version, and get in touch with the various contributors via the information in the acknowledgement section. Please consider using the Original Versions of the fonts whenever possible.
+
+1.19 What do you mean in condition 4 of the OFL's permissions and conditions? Can you provide examples of abusive promotion / endorsement / advertisement vs. normal acknowledgement?
+The intent is that the goodwill and reputation of the author(s) should not be used in a way that makes it sound like the original author(s) endorse or approve of a specific Modified Version or software bundle. For example, it would not be right to advertise a word processor by naming the author(s) in a listing of software features, or to promote a Modified Version on a web site by saying "designed by ...". However, it would be appropriate to acknowledge the author(s) if your software package has a list of people who deserve thanks. We realize that this can seem to be a grey area, but the standard used to judge an acknowledgement is that if the acknowledgement benefits the author(s) it is allowed, but if it primarily benefits other parties, or could reflect poorly on the author(s), then it is not.
+
+1.20 I'm writing a small app for mobile platforms, do I need to include the whole package?
+If you bundle a font under the OFL with your mobile app you must comply with the terms of the license. At a minimum you must include the copyright statement, the license notice and the license text. A mention of this information in your About box or Changelog, with a link to where the font package is from, is good practice, and the extra space needed to carry these items is very small. You do not, however, need to include the full contents of the font package - only the fonts you use and the copyright and license that apply to them. For example, if you only use the regular weight in your app, you do not need to include the italic and bold versions.
+
+1.21 What about including OFL fonts by default in my firmware or dedicated operating system?
+Many such systems are restricted and turned into appliances so that users cannot study or modify them. Using open fonts to increase quality and language coverage is a great idea, but you need to be aware that if there is a way for users to extract fonts you cannot legally prevent them from doing that. The fonts themselves, including any changes you make to them, must be distributed under the OFL even if your firmware has a more restrictive license. If you do transform the fonts and change their formats when you include them in your firmware you must respect any names reserved by the font authors via the RFN mechanism and pick your own font name. Alternatively if you directly add a font under the OFL to the font folder of your firmware without modifying or optimizing it you are simply bundling the font like with any other software collection, and do not need to make any further changes.
+
+1.22 Can I make and publish CMS themes or templates that use OFL fonts? Can I include the fonts themselves in the themes or templates? Can I sell the whole package?
+Yes, you are very welcome to integrate open fonts into themes and templates for your preferred CMS and make them more widely available. Remember that you can only sell the fonts and your CMS add-on as part of a software bundle. (See 1.4 for details and examples about selling bundles).
+
+1.23 Can OFL fonts be included in services that deliver fonts to the desktop from remote repositories? Even if they contain both OFL and non-OFL fonts?
+Yes. Some foundries have set up services to deliver fonts to subscribers directly to desktops from their online repositories; similarly, plugins are available to preview and use fonts directly in your design tool or publishing suite. These services may mix open and restricted fonts in the same channel, however they should make a clear distinction between them to users. These services should also not hinder users (such as through DRM or obfuscation mechanisms) from extracting and using the OFL fonts in other environments, or continuing to use OFL fonts after subscription terms have ended, as those uses are specifically allowed by the OFL.
+
+1.24 Can services that provide or distribute OFL fonts restrict my use of them?
+No. The terms of use of such services cannot replace or restrict the terms of the OFL, as that would be the same as distributing the fonts under a different license, which is not allowed. You are still entitled to use, modify and redistribute them as the original authors have intended outside of the sole control of that particular distribution channel. Note, however, that the fonts provided by these services may differ from the Original Versions.
+
+
+2 USING OFL FONTS FOR WEBPAGES AND ONLINE WEB FONT SERVICES
+
+NOTE: This section often refers to a separate paper on 'Web Fonts & RFNs'. This is available at http://scripts.sil.org/OFL_web_fonts_and_RFNs
+
+2.1 Can I make webpages using these fonts?
+Yes! Go ahead! Using CSS (Cascading Style Sheets) is recommended. Your three best options are:
+- referring directly in your stylesheet to open fonts which may be available on the user's system
+- providing links to download the full package of the font - either from your own website or from elsewhere - so users can install it themselves
+- using @font-face to distribute the font directly to browsers. This is recommended and explicitly allowed by the licensing model because it is distribution. The font file itself is distributed with other components of the webpage. It is not embedded in the webpage but referenced through a web address which will cause the browser to retrieve and use the corresponding font to render the webpage (see 1.11 and 1.15 for details related to embedding fonts into documents). As you take advantage of the @font-face cross-platform standard, be aware that web fonts are often tuned for a web environment and not intended for installation and use outside a browser. The reasons in favour of using web fonts are to allow design of dynamic text elements instead of static graphics, to make it easier for content to be localized and translated, indexed and searched, and all this with cross-platform open standards without depending on restricted extensions or plugins. You should check the CSS cascade (the order in which fonts are being called or delivered to your users) when testing.
+
+2.2 Can I make and use WOFF (Web Open Font Format) versions of OFL fonts?
+Yes, but you need to be careful. A change in font format normally is considered modification, and Reserved Font Names (RFNs) cannot be used. Because of the design of the WOFF format, however, it is possible to create a WOFF version that is not considered modification, and so would not require a name change. You are allowed to create, use and distribute a WOFF version of an OFL font without changing the font name, but only if:
+
+- the original font data remains unchanged except for WOFF compression, and
+- WOFF-specific metadata is either omitted altogether or present and includes, unaltered, the contents of all equivalent metadata in the original font.
+
+If the original font data or metadata is changed, or the WOFF-specific metadata is incomplete, the font must be considered a Modified Version, the OFL restrictions would apply and the name of the font must be changed: any RFNs cannot be used and copyright notices and licensing information must be included and cannot be deleted or modified. You must come up with a unique name - we recommend one corresponding to your domain or your particular web application. Be aware that only the original author(s) can use RFNs. This is to prevent collisions between a derivative tuned to your audience and the original upstream version and so to reduce confusion.
+
+Please note that most WOFF conversion tools and online services do not meet the two requirements listed above, and so their output must be considered a Modified Version. So be very careful and check to be sure that the tool or service you're using is compressing unchanged data and completely and accurately reflecting the original font metadata.
+
+2.3 What about other web font formats such as EOT/EOTLite/CWT/etc.?
+In most cases these formats alter the original font data more than WOFF, and do not completely support appropriate metadata, so their use must be considered modification and RFNs may not be used. However, there may be certain formats or usage scenarios that may allow the use of RFNs. See http://scripts.sil.org/OFL_web_fonts_and_RFNs
+
+2.4 Can I make OFL fonts available through web font online services?
+Yes, you are welcome to include OFL fonts in online web font services as long as you properly meet all the conditions of the license. The origin and open status of the font should be clear among the other fonts you are hosting. Authorship, copyright notices and license information must be sufficiently visible to your users or subscribers so they know where the font comes from and the rights granted by the author(s). Make sure the font file contains the needed copyright notice(s) and licensing information in its metadata. Please double-check the accuracy of every field to prevent contradictory information. Other font formats, including EOT/EOTLite/CWT and superior alternatives like WOFF, already provide fields for this information. Remember that if you modify the font within your library or convert it to another format for any reason the OFL restrictions apply and you need to change the names accordingly. Please respect the author's wishes as expressed in the OFL and do not misrepresent original designers and their work. Don't lump quality open fonts together with dubious freeware or public domain fonts. Consider how you can best work with the original designers and foundries, support their efforts and generate goodwill that will benefit your service. (See 1.17 for details related to URL-based access restrictions methods or DRM mechanisms).
+
+2.5 Some web font formats and services provide ways of "optimizing" the font for a particular website or web application; is that allowed?
+Yes, it is permitted, but remember that these optimized versions are Modified Versions and so must follow OFL requirements like appropriate renaming. Also you need to bear in mind the other important parameters beyond compression, speed and responsiveness: you need to consider the audience of your particular website or web application, as choosing some optimization parameters may turn out to be less than ideal for them. Subsetting by removing certain glyphs or features may seriously limit functionality of the font in various languages that your users expect. It may also introduce degradation of quality in the rendering or specific bugs on the various target platforms compared to the original font from upstream. In other words, remember that one person's optimized font may be another person's missing feature. Various advanced typographic features (OpenType, Graphite or AAT) are also available through CSS and may provide the desired effects without the need to modify the font.
+
+2.6 Is subsetting a web font considered modification?
+Yes. Removing any parts of the font when delivering a web font to a browser, including unused glyphs and smart font code, is considered modification. This is permitted by the OFL but would not normally allow the use of RFNs. Some newer subsetting technologies may be able to subset in a way that allows users to effectively have access to the complete font, including smart font behaviour. See 2.8 and http://scripts.sil.org/OFL_web_fonts_and_RFNs
+
+2.7 Are there any situations in which a modified web font could use RFNs?
+Yes. If a web font is optimized only in ways that preserve Functional Equivalence (see 2.8), then it may use RFNs, as it reasonably represents the Original Version and respects the intentions of the author(s) and the main purposes of the RFN mechanism (avoids collisions, protects authors, minimizes support, encourages derivatives). However this is technically very difficult and often impractical, so a much better scenario is for the web font service or provider to sign a separate agreement with the author(s) that allows the use of RFNs for Modified Versions.
+
+2.8 How do you know if an optimization to a web font preserves Functional Equivalence?
+Functional Equivalence is described in full in the 'Web fonts and RFNs' paper at http://scripts.sil.org/OFL_web_fonts_and_RFNs, in general, an optimized font is deemed to be Functionally Equivalent (FE) to the Original Version if it:
+
+- Supports the same full character inventory. If a character can be properly displayed using the Original Version, then that same character, encoded correctly on a web page, will display properly.
+- Provides the same smart font behavior. Any dynamic shaping behavior that works with the Original Version should work when optimized, unless the browser or environment does not support it. There does not need to be guaranteed support in the client, but there should be no forced degradation of smart font or shaping behavior, such as the removal or obfuscation of OpenType, Graphite or AAT tables.
+- Presents text with no obvious degradation in visual quality. The lettershapes should be equally (or more) readable, within limits of the rendering platform.
+- Preserves original author, project and license metadata. At a minimum, this should include: Copyright and authorship; The license as stated in the Original Version, whether that is the full text of the OFL or a link to the web version; Any RFN declarations; Information already present in the font or documentation that points back to the Original Version, such as a link to the project or the author's website.
+
+If an optimized font meets these requirements, and so is considered to be FE, then it's very likely that the original author would feel that the optimized font is a good and reasonable equivalent. If it falls short of any of these requirements, the optimized font does not reasonably represent the Original Version, and so should be considered to be a Modified Version. Like other Modified Versions, it would not be allowed to use any RFNs and you simply need to pick your own font name.
+
+2.9 Isn't use of web fonts another form of embedding?
+No. Unlike embedded fonts in a PDF, web fonts are not an integrated part of the document itself. They are not specific to a single document and are often applied to thousands of documents around the world. The font data is not stored alongside the document data and often originates from a different location. The ease by which the web fonts used by a document may be identified and downloaded for desktop use demonstrates that they are philosophically and technically separate from the web pages that specify them. See http://scripts.sil.org/OFL_web_fonts_and_RFNs
+
+2.10 So would it be better to not use RFNs at all if you want your font to be distributed by a web fonts service?
+No. Although the OFL does not require authors to use RFNs, the RFN mechanism is an important part of the OFL model and completely compatible with web font services. If that web font service modifies the fonts, then the best solution is to sign a separate agreement for the use of any RFNs. It is perfectly valid for an author to not declare any RFNs, but before they do so they need to fully understand the benefits they are giving up, and the overall negative effect of allowing many different versions bearing the same name to be widely distributed. As a result, we don't generally recommend it.
+
+2.11 What should an agreement for the use of RFNs say? Are there any examples?
+There is no prescribed format for this agreement, as legal systems vary, and no recommended examples. Authors may wish to add specific clauses to further restrict use, require author review of Modified Versions, establish user support mechanisms or provide terms for ending the agreement. Such agreements are usually not public, and apply only to the main parties. However, it would be very beneficial for web font services to clearly state when they have established such agreements, so that the public understands clearly that their service is operating appropriately.
+
+See the separate paper on 'Web Fonts & RFNs' for in-depth discussion of issues related to the use of RFNs for web fonts. This is available at http://scripts.sil.org/OFL_web_fonts_and_RFNs
+
+
+3 MODIFYING OFL-LICENSED FONTS
+
+3.1 Can I change the fonts? Are there any limitations to what things I can and cannot change?
+You are allowed to change anything, as long as such changes do not violate the terms of the license. In other words, you are not allowed to remove the copyright statement(s) from the font, but you could put additional information into it that covers your contribution. See the placeholders in the OFL header template for recommendations on where to add your own statements. (Remember that, when authors have reserved names via the RFN mechanism, you need to change the internal names of the font to your own font name when making your modified version even if it is just a small change.)
+
+3.2 I have a font that needs a few extra glyphs - can I take them from an OFL licensed font and copy them into mine?
+Yes, but if you distribute that font to others it must be under the OFL, and include the information mentioned in condition 2 of the license.
+
+3.3 Can I charge people for my additional work? In other words, if I add a bunch of special glyphs or OpenType/Graphite/AAT code, can I sell the enhanced font?
+Not by itself. Derivative fonts must be released under the OFL and cannot be sold by themselves. It is permitted, however, to include them in a larger software package (such as text editors, office suites or operating systems), even if the larger package is sold. In that case, you are strongly encouraged, but not required, to also make that derived font easily and freely available outside of the larger package.
+
+3.4 Can I pay someone to enhance the fonts for my use and distribution?
+Yes. This is a good way to fund the further development of the fonts. Keep in mind, however, that if the font is distributed to others it must be under the OFL. You won't be able to recover your investment by exclusively selling the font, but you will be making a valuable contribution to the community. Please remember how you have benefited from the contributions of others.
+
+3.5 I need to make substantial revisions to the font to make it work with my program. It will be a lot of work, and a big investment, and I want to be sure that it can only be distributed with my program. Can I restrict its use?
+No. If you redistribute a Modified Version of the font it must be under the OFL. You may not restrict it in any way beyond what the OFL permits and requires. This is intended to ensure that all released improvements to the fonts become available to everyone. But you will likely get an edge over competitors by being the first to distribute a bundle with the enhancements. Again, please remember how you have benefited from the contributions of others.
+
+3.6 Do I have to make any derivative fonts (including extended source files, build scripts, documentation, etc.) publicly available?
+No, but please consider sharing your improvements with others. You may find that you receive in return more than what you gave.
+
+3.7 If a trademark is claimed in the OFL font, does that trademark need to remain in modified fonts?
+Yes. Any trademark notices must remain in any derivative fonts to respect trademark laws, but you may add any additional trademarks you claim, officially registered or not. For example if an OFL font called "Foo" contains a notice that "Foo is a trademark of Acme", then if you rename the font to "Bar" when creating a Modified Version, the new trademark notice could say "Foo is a trademark of Acme Inc. - Bar is a trademark of Roadrunner Technologies Ltd.". Trademarks work alongside the OFL and are not subject to the terms of the licensing agreement. The OFL does not grant any rights under trademark law. Bear in mind that trademark law varies from country to country and that there are no international trademark conventions as there are for copyright. You may need to significantly invest in registering and defending a trademark for it to remain valid in the countries you are interested in. This may be costly for an individual independent designer.

+3.8 If I commit changes to a font (or publish a branch in a DVCS) as part of a public open source software project, do I have to change the internal font names?
+Only if there are declared RFNs. Making a public commit or publishing a public branch is effectively redistributing your modifications, so any change to the font will require that you do not use the RFNs. Even if there are no RFNs, it may be useful to change the name or add a suffix indicating that a particular version of the font is still in development and not released yet. This will clearly indicate to users and fellow designers that this particular font is not ready for release yet. See section 5 for more details.
+
+
+4 LICENSING YOUR ORIGINAL FONTS UNDER THE OFL
+
+4.1 Can I use the SIL OFL for my own fonts?
+Yes! We heartily encourage everyone to use the OFL to distribute their own original fonts. It is a carefully constructed license that allows great freedom along with enough artistic integrity protection for the work of the authors as well as clear rules for other contributors and those who redistribute the fonts. The licensing model is used successfully by various organisations, both for-profit and not-for-profit, to release fonts of varying levels of scope and complexity.
+
+4.2 What do I have to do to apply the OFL to my font?
+If you want to release your fonts under the OFL, we recommend you do the following:
+
+4.2.1 Put your copyright and Reserved Font Names information at the beginning of the main OFL.txt file in place of the dedicated placeholders (marked with the <> characters). Include this file in your release package.
+
+4.2.2 Put your copyright and the OFL text with your chosen Reserved Font Name(s) into your font files (the copyright and license fields). A link to the OFL text on the OFL web site is an acceptable (but not recommended) alternative. Also add this information to any other components (build scripts, glyph databases, documentation, test files, etc). Accurate metadata in your font files is beneficial to you as an increasing number of applications are exposing this information to the user. For example, clickable links can bring users back to your website and let them know about other work you have done or services you provide. Depending on the format of your fonts and sources, you can use template human-readable headers or machine-readable metadata. You should also double-check that there is no conflicting metadata in the font itself contradicting the license, such as the fstype bits in the os2 table or fields in the name table.
+
+4.2.3 Write an initial FONTLOG.txt for your font and include it in the release package (see Section 6 and Appendix A for details including a template).
+
+4.2.4 Include the relevant practical documentation on the license by adding the current OFL-FAQ.txt file in your package.
+
+4.2.5 If you wish you can use the OFL graphics (http://scripts.sil.org/OFL_logo) on your website.
+
+4.3 Will you make my font OFL for me?
+We won't do the work for you. We can, however, try to answer your questions, unfortunately we do not have the resources to review and check your font packages for correct use of the OFL. We recommend you turn to designers, foundries or consulting companies with experience in doing open font design to provide this service to you.
+
+4.4 Will you distribute my OFL font for me?
+No, although if the font is of sufficient quality and general interest we may include a link to it on our partial list of OFL fonts on the OFL web site. You may wish to consider other open font catalogs or hosting services, such as the Unifont Font Guide (http://unifont.org/fontguide), The League of Movable Type (http://theleagueofmovabletype.com) or the Open Font Library (http://openfontlibrary.org/), which despite the name has no direct relationship to the OFL or SIL. We do not endorse any particular catalog or hosting service - it is your responsibility to determine if the service is right for you and if it treats authors with fairness.
+
+4.5 Why should I use the OFL for my fonts?
+- to meet needs for fonts that can be modified to support lesser-known languages
+- to provide a legal and clear way for people to respect your work but still use it (and reduce piracy)
+- to involve others in your font project
+- to enable your fonts to be expanded with new weights and improved writing system/language support
+- to allow more technical font developers to add features to your design (such as OpenType, Graphite or AAT support)
+- to renew the life of an old font lying on your hard drive with no business model
+- to allow your font to be included in Libre Software operating systems like Ubuntu
+- to give your font world status and wide, unrestricted distribution
+- to educate students about quality typeface and font design
+- to expand your test base and get more useful feedback
+- to extend your reach to new markets when users see your metadata and go to your website
+- to get your font more easily into one of the web font online services
+- to attract attention for your commercial fonts
+- to make money through web font services
+- to make money by bundling fonts with applications
+- to make money adjusting and extending existing open fonts
+- to get a better chance that foundations/NGOs/charities/companies who commission fonts will pick you
+- to be part of a sharing design and development community
+- to give back and contribute to a growing body of font sources
+
+
+5 CHOOSING RESERVED FONT NAMES
+
+5.1 What are Reserved Font Names?
+These are font names, or portions of font names, that the author has chosen to reserve for use only with the Original Version of the font, or for Modified Version(s) created by the original author.
+
+5.2 Why can't I use the Reserved Font Names in my derivative font names? I'd like people to know where the design came from.
+The best way to acknowledge the source of the design is to thank the original authors and any other contributors in the files that are distributed with your revised font (although no acknowledgement is required). The FONTLOG is a natural place to do this. Reserved Font Names ensure that the only fonts that have the original names are the unmodified Original Versions. This allows designers to maintain artistic integrity while allowing collaboration to happen. It eliminates potential confusion and name conflicts. When choosing a name, be creative and avoid names that reuse almost all the same letters in the same order or sound like the original. It will help everyone if Original Versions and Modified Versions can easily be distinguished from one another and from other derivatives. Any substitution and matching mechanism is outside the scope of the license.
+
+5.3 What do you mean by "primary name as presented to the user"? Are you referring to the font menu name?
+Yes, this applies to the font menu name and other mechanisms that specify a font in a document. It would be fine, however, to keep a text reference to the original fonts in the description field, in your modified source file or in documentation provided alongside your derivative as long as no one could be confused that your modified source is the original. But you cannot use the Reserved Font Names in any way to identify the font to the user (unless the Copyright Holder(s) allow(s) it through a separate agreement). Users who install derivatives (Modified Versions) on their systems should not see any of the original Reserved Font Names in their font menus, for example. Again, this is to ensure that users are not confused and do not mistake one font for another and so expect features only another derivative or the Original Version can actually offer.
+
+5.4 Am I not allowed to use any part of the Reserved Font Names?
+You may not use individual words from the Reserved Font Names, but you would be allowed to use parts of words, as long as you do not use any word from the Reserved Font Names entirely. We do not recommend using parts of words because of potential confusion, but it is allowed. For example, if "Foobar" was a Reserved Font Name, you would be allowed to use "Foo" or "bar", although we would not recommend it. Such an unfortunate choice would confuse the users of your fonts as well as make it harder for other designers to contribute.
+
+5.5 So what should I, as an author, identify as Reserved Font Names?
+Original authors are encouraged to name their fonts using clear, distinct names, and only declare the unique parts of the name as Reserved Font Names. For example, the author of a font called "Foobar Sans" would declare "Foobar" as a Reserved Font Name, but not "Sans", as that is a common typographical term, and may be a useful word to use in a derivative font name. Reserved Font Names should also be single words for simplicity and legibility. A font called "Flowing River" should have Reserved Font Names "Flowing" and "River", not "Flowing River". You also need to be very careful about reserving font names which are already linked to trademarks (whether registered or not) which you do not own.
+
+5.6 Do I, as an author, have to identify any Reserved Font Names?
+No. RFNs are optional and not required, but we encourage you to use them. This is primarily to avoid confusion between your work and Modified Versions. As an author you can release a font under the OFL and not declare any Reserved Font Names. There may be situations where you find that using no RFNs and letting your font be changed and modified - including any kind of modification - without having to change the original name is desirable. However you need to be fully aware of the consequences. There will be no direct way for end-users and other designers to distinguish your Original Version from many Modified Versions that may be created. You have to trust whoever is making the changes and the optimizations to not introduce problematic changes. The RFNs you choose for your own creation have value to you as an author because they allow you to maintain artistic integrity and keep some control over the distribution channel to your end-users. For discussion of RFNs and web fonts see section 2.
+
+5.7 Are any names (such as the main font name) reserved by default?
+No. That is a change to the license as of version 1.1. If you want any names to be Reserved Font Names, they must be specified after the copyright statement(s).
+
+5.8 Is there any situation in which I can use Reserved Font Names for a Modified Version?
+The Copyright Holder(s) can give certain trusted parties the right to use any of the Reserved Font Names through separate written agreements. For example, even if "Foobar" is a RFN, you could write up an agreement to give company "XYZ" the right to distribute a modified version with a name that includes "Foobar". This allows for freedom without confusion. The existence of such an agreement should be made as clear as possible to downstream users and designers in the distribution package and the relevant documentation. They need to know if they are a party to the agreement or not and what they are practically allowed to do or not even if all the details of the agreement are not public.
+
+5.9 Do font rebuilds require a name change? Do I have to change the name of the font when my packaging workflow includes a full rebuild from source?
+Yes, all rebuilds which change the font data and the smart code are Modified Versions and the requirements of the OFL apply: you need to respect what the Author(s) have chosen in terms of Reserved Font Names. However if a package (or installer) is simply a wrapper or a compressed structure around the final font - leaving them intact on the inside - then no name change is required. Please get in touch with the author(s) and copyright holder(s) to inquire about the presence of font sources beyond the final font file(s) and the recommended build path. That build path may very well be non-trivial and hard to reproduce accurately by the maintainer. If a full font build path is made available by the upstream author(s) please be aware that any regressions and changes you may introduce when doing a rebuild for packaging purposes is your own responsibility as a package maintainer since you are effectively creating a separate branch. You should make it very clear to your users that your rebuilt version is not the canonical one from upstream.
+
+5.10 Can I add other Reserved Font Names when making a derivative font?
+Yes. List your additional Reserved Font Names after your additional copyright statement, as indicated with example placeholders at the top of the OFL.txt file. Be sure you do not remove any existing RFNs but only add your own. RFN statements should be placed next to the copyright statement of the relevant author as indicated in the OFL.txt template to make them visible to designers wishing to make their separate version.
+
+
+6 ABOUT THE FONTLOG
+
+6.1 What is this FONTLOG thing exactly?
+It has three purposes: 1) to provide basic information on the font to users and other designers and developers, 2) to document changes that have been made to the font or accompanying files, either by the original authors or others, and 3) to provide a place to acknowledge authors and other contributors. Please use it!
+
+6.2 Is the FONTLOG required?
+It is not a requirement of the license, but we strongly recommend you have one.
+
+6.3 Am I required to update the FONTLOG when making Modified Versions?
+No, but users, designers and other developers might get very frustrated with you if you don't. People need to know how derivative fonts differ from the original, and how to take advantage of the changes, or build on them. There are utilities that can help create and maintain a FONTLOG, such as the FONTLOG support in FontForge.
+
+6.4 What should the FONTLOG look like?
+It is typically a separate text file (FONTLOG.txt), but can take other formats. It commonly includes these four sections:
+
+- brief header describing the FONTLOG itself and name of the font family
+- Basic Font Information - description of the font family, purpose and breadth
+- ChangeLog - chronological listing of changes
+- Acknowledgements - list of authors and contributors with contact information
+
+It could also include other sections, such as: where to find documentation, how to make contributions, information on contributing organizations, source code details, and a short design guide. See Appendix A for an example FONTLOG.
+
+
+7 MAKING CONTRIBUTIONS TO OFL PROJECTS
+
+7.1 Can I contribute work to OFL projects?
+In many cases, yes. It is common for OFL fonts to be developed by a team of people who welcome contributions from the wider community. Contact the original authors for specific information on how to participate in their projects.
+
+7.2 Why should I contribute my changes back to the original authors?
+It would benefit many people if you contributed back in response to what you've received. Your contributions and improvements to the fonts and other components could be a tremendous help and would encourage others to contribute as well and 'give back'. You will then benefit from other people's contributions as well. Sometimes maintaining your own separate version takes more effort than merging back with the original. Be aware that any contributions, however, must be either your own original creation or work that you own, and you may be asked to affirm that clearly when you contribute.
+
+7.3 I've made some very nice improvements to the font. Will you consider adopting them and putting them into future Original Versions?
+Most authors would be very happy to receive such contributions. Keep in mind that it is unlikely that they would want to incorporate major changes that would require additional work on their end. Any contributions would likely need to be made for all the fonts in a family and match the overall design and style. Authors are encouraged to include a guide to the design with the fonts. It would also help to have contributions submitted as patches or clearly marked changes - the use of smart source revision control systems like subversion, mercurial, git or bzr is a good idea. Please follow the recommendations given by the author(s) in terms of preferred source formats and configuration parameters for sending contributions. If this is not indicated in a FONTLOG or other documentation of the font, consider asking them directly. Examples of useful contributions are bug fixes, additional glyphs, stylistic alternates (and the smart font code to access them) or improved hinting. Keep in mind that some kinds of changes (esp. hinting) may be technically difficult to integrate.
+
+7.4 How can I financially support the development of OFL fonts?
+It is likely that most authors of OFL fonts would accept financial contributions - contact them for instructions on how to do this. Such contributions would support future development. You can also pay for others to enhance the fonts and contribute the results back to the original authors for inclusion in the Original Version.
+
+
+8 ABOUT THE LICENSE ITSELF
+
+8.1 I see that this is version 1.1 of the license. Will there be later changes?
+Version 1.1 is the first minor revision of the OFL. We are confident that version 1.1 will meet most needs, but are open to future improvements. Any revisions would be for future font releases, and previously existing licenses would remain in effect. No retroactive changes are possible, although the Copyright Holder(s) can re-release the font under a revised OFL. All versions will be available on our web site: http://scripts.sil.org/OFL.
+
+8.2 Does this license restrict the rights of the Copyright Holder(s)?
+No. The Copyright Holder(s) still retain(s) all the rights to their creation; they are only releasing a portion of it for use in a specific way. For example, the Copyright Holder(s) may choose to release a 'basic' version of their font under the OFL, but sell a restricted 'enhanced' version under a different license. They may also choose to release the same font under both the OFL and some other license. Only the Copyright Holder(s) can do this, and doing so does not change the terms of the OFL as it applies to that font.
+
+8.3 Is the OFL a contract or a license?
+The OFL is a worldwide license based on international copyright agreements and conventions. It is not a contract and so does not require you to sign it to have legal validity. By using, modifying and redistributing components under the OFL you indicate that you accept the license.
+
+8.4 I really like the terms of the OFL, but want to change it a little. Am I allowed to take ideas and actual wording from the OFL and put them into my own custom license for distributing my fonts?
+We strongly recommend against creating your very own unique open licensing model. Using a modified or derivative license will likely cut you off - along with the font(s) under that license - from the community of designers using the OFL, potentially expose you and your users to legal liabilities, and possibly put your work and rights at risk. The OFL went though a community and legal review process that took years of effort, and that review is only applicable to an unmodified OFL. The text of the OFL has been written by SIL (with review and consultation from the community) and is copyright (c) 2005-2013 SIL International. You may re-use the ideas and wording (in part, not in whole) in another non-proprietary license provided that you call your license by another unambiguous name, that you do not use the preamble, that you do not mention SIL and that you clearly present your license as different from the OFL so as not to cause confusion by being too similar to the original. If you feel the OFL does not meet your needs for an open license, please contact us.
+
+8.5 Can I translate the license and the FAQ into other languages?
+SIL certainly recognises the need for people who are not familiar with English to be able to understand the OFL and its use. Making the license very clear and readable has been a key goal for the OFL, but we know that people understand their own language best.
+
+If you are an experienced translator, you are very welcome to translate the OFL and OFL-FAQ so that designers and users in your language community can understand the license better. But only the original English version of the license has legal value and has been approved by the community. Translations do not count as legal substitutes and should only serve as a way to explain the original license. SIL - as the author and steward of the license for the community at large - does not approve any translation of the OFL as legally valid because even small translation ambiguities could be abused and create problems.
+
+SIL gives permission to publish unofficial translations into other languages provided that they comply with the following guidelines:
+
+- Put the following disclaimer in both English and the target language stating clearly that the translation is unofficial:
+
+"This is an unofficial translation of the SIL Open Font License into <language_name>. It was not published by SIL International, and does not legally state the distribution terms for fonts that use the OFL. A release under the OFL is only valid when using the original English text. However, we recognize that this unofficial translation will help users and designers not familiar with English to better understand and use the OFL. We encourage designers who consider releasing their creation under the OFL to read the OFL-FAQ in their own language if it is available. Please go to http://scripts.sil.org/OFL for the official version of the license and the accompanying OFL-FAQ."
+
+- Keep your unofficial translation current and update it at our request if needed, for example if there is any ambiguity which could lead to confusion.
+
+If you start such a unofficial translation effort of the OFL and OFL-FAQ please let us know.
+
+8.6 Does the OFL have an explicit expiration term?
+No, the implicit intent of the OFL is that the permissions granted are perpetual and irrevocable.
+
+
+9 ABOUT SIL INTERNATIONAL
+
+9.1 Who is SIL International and what do they do?
+SIL serves language communities worldwide, building their capacity for sustainable language development, by means of research, translation, training and materials development. SIL makes its services available to all without regard to religious belief, political ideology, gender, race, or ethnic background. SIL's members and volunteers share a Christian commitment.
+
+9.2 What does this have to do with font licensing?
+The ability to read, write, type and publish in one's own language is one of the most critical needs for millions of people around the world. This requires fonts that are widely available and support lesser-known languages. SIL develops - and encourages others to develop - a complete stack of writing systems implementation components available under open licenses. This open stack includes input methods, smart fonts, smart rendering libraries and smart applications. There has been a need for a common open license that is specifically applicable to fonts and related software (a crucial component of this stack), so SIL developed the SIL Open Font License with the help of the Free/Libre and Open Source Software community.
+
+9.3 How can I contact SIL?
+Our main web site is: http://www.sil.org/
+Our site about complex scripts is: http://scripts.sil.org/
+Information about this license (and contact information) is at: http://scripts.sil.org/OFL

+future versions. Make sure you read through the
+SIL Unicode Roman FAQ (http://scripts.sil.org/ComplexRomanFontFAQ).

+Many problems can be solved, or at least explained, through an understanding
+of the encoding and use of the fonts. Here are some basic hints:
+
+Encoding:
+The fonts are encoded according to Unicode, so your application must support
+Unicode text in order to access letters other than the standard alphabet.
+Most Windows applications provide basic Unicode support. You will, however,
+need some way of entering Unicode text into your document.
+
+Keyboarding:
+This font does not include any keyboarding helps or utilities. It uses the
+built-in keyboards of the operating system. You will need to install the
+appropriate keyboard and input method for the characters of the language you
+wish to use. If you want to enter characters that are not supported by any
+system keyboard, the Keyman program (www.tavultesoft.com) can be helpful
+on Windows systems. Also available for Windows is MSKLC
+(http://www.microsoft.com/globaldev/tools/msklc.mspx).
+For Linux systems such as Ubuntu, KMFL (http://kmfl.sourceforge.net/)
+is available. Ukelele (http://scripts.sil.org/ukelele) is available for
+Mac OS X versions 10.2 and later.
+
+For other platforms, KMFL (http://kmfl.sourceforge.net/),
+XKB (http://www.x.org/wiki/XKB) or Ukelele (http://scripts.sil.org/ukelele)
+can be helpful.
+
+If you want to enter characters that are not supported by any system
+keyboard, and to access the full Unicode range, we suggest you use
+gucharmap, kcharselect on Ubuntu or similar software.
+
+Another method of entering some symbols is provided by a few applications such
+as Adobe InDesign or OpenOffice.org. They can display a glyph palette or input
+dialog that shows all the glyphs (symbols) in a font and allow you to enter
+them by clicking on the glyph you want.
+
+Rendering:
+This font is designed to work with Graphite or Opentype advanced font
+technologies. To take advantage of the advanced typographic
+capabilities of this font, you must be using applications that provide an
+adequate level of support for Graphite or OpenType. See "Applications
+that provide an adequate level of support for SIL Unicode Roman fonts"
+(http://scripts.sil.org/Complex_AdLvSup).

+ 2013-05-02 (0.2.8):
+
+ * Use quadratic probing. When the capacity is power of 2, stepping function
+ i*(i+1)/2 guarantees to traverse each bucket. It is better than double
+ hashing on cache performance and is more robust than linear probing.
+
+ In theory, double hashing should be more robust than quadratic probing.
+ However, my implementation is probably not for large hash tables, because
+ the second hash function is closely tied to the first hash function,
+ which reduce the effectiveness of double hashing.
+
+ Reference: http://research.cs.vt.edu/AVresearch/hashing/quadratic.php
+
+ 2011-12-29 (0.2.7):
+
+ * Minor code clean up; no actual effect.
+
+ 2011-09-16 (0.2.6):
+
+ * The capacity is a power of 2. This seems to dramatically improve the
+ speed for simple keys. Thank Zilong Tan for the suggestion. Reference:
+
+ - http://code.google.com/p/ulib/
+ - http://nothings.org/computer/judy/
+
+ * Allow to optionally use linear probing which usually has better
+ performance for random input. Double hashing is still the default as it
+ is more robust to certain non-random input.
+
+ * Added Wang's integer hash function (not used by default). This hash
+ function is more robust to certain non-random input.
+
+ 2011-02-14 (0.2.5):
+
+ * Allow to declare global functions.
+
+ 2009-09-26 (0.2.4):
+
+ * Improve portability
+
+ 2008-09-19 (0.2.3):
+
+ * Corrected the example
+ * Improved interfaces
+
+ 2008-09-11 (0.2.2):
+
+ * Improved speed a little in kh_put()
+
+ 2008-09-10 (0.2.1):
+
+ * Added kh_clear()
+ * Fixed a compiling error
+
+ 2008-09-02 (0.2.0):
+
+ * Changed to token concatenation which increases flexibility.
+
+ 2008-08-31 (0.1.2):

+ writes out PNG/BMP/TGA images to C stdio - Sean Barrett 2010-2015
+ no warranty implied; use at your own risk
+
+ Before #including,
+
+ #define STB_IMAGE_WRITE_IMPLEMENTATION
+
+ in the file that you want to have the implementation.
+
+ Will probably not work correctly with strict-aliasing optimizations.
+
+ABOUT:
+
+ This header file is a library for writing images to C stdio. It could be
+ adapted to write to memory or a general streaming interface; let me know.
+
+ The PNG output is not optimal; it is 20-50% larger than the file
+ written by a decent optimizing implementation. This library is designed
+ for source code compactness and simplicity, not optimal image file size
+ or run-time performance.
+
+BUILDING:
+
+ You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
+ You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
+ malloc,realloc,free.
+ You can define STBIW_MEMMOVE() to replace memmove()
+
+USAGE:
+
+ There are four functions, one for each image file format:
+
+ int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
+ int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
+ int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
+ int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
+
+ There are also four equivalent functions that use an arbitrary write function. You are
+ expected to open/close your file-equivalent before and after calling these:
+
+ int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes);
+ int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
+ int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
+ int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
+
+ where the callback is:
+ void stbi_write_func(void *context, void *data, int size);
+
+ You can define STBI_WRITE_NO_STDIO to disable the file variant of these
+ functions, so the library will not use stdio.h at all. However, this will
+ also disable HDR writing, because it requires stdio for formatted output.
+
+ Each function returns 0 on failure and non-0 on success.
+
+ The functions create an image file defined by the parameters. The image
+ is a rectangle of pixels stored from left-to-right, top-to-bottom.
+ Each pixel contains 'comp' channels of data stored interleaved with 8-bits
+ per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
+ monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
+ The *data pointer points to the first byte of the top-left-most pixel.
+ For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
+ a row of pixels to the first byte of the next row of pixels.
+
+ PNG creates output files with the same number of components as the input.
+ The BMP format expands Y to RGB in the file format and does not
+ output alpha.
+
+ PNG supports writing rectangles of data even when the bytes storing rows of
+ data are not consecutive in memory (e.g. sub-rectangles of a larger image),
+ by supplying the stride between the beginning of adjacent rows. The other
+ formats do not. (Thus you cannot write a native-format BMP through the BMP
+ writer, both because it is in BGR order and because it may have padding
+ at the end of the line.)
+
+ HDR expects linear float data. Since the format is always 32-bit rgb(e)
+ data, alpha (if provided) is discarded, and for monochrome data it is
+ replicated across all three channels.
+
+ TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
+ data, set the global variable 'stbi_write_tga_with_rle' to 0.

+//
+// USAGE
+//
+// Include this file in whatever places neeed to refer to it. In ONE C/C++
+// file, write:
+// #define STB_TRUETYPE_IMPLEMENTATION
+// before the #include of this file. This expands out the actual
+// implementation into that C/C++ file.
+//
+// To make the implementation private to the file that generates the implementation,
+// #define STBTT_STATIC
+//
+// Simple 3D API (don't ship this, but it's fine for tools and quick start)
+// stbtt_BakeFontBitmap() -- bake a font to a bitmap for use as texture
+// stbtt_GetBakedQuad() -- compute quad to draw for a given char
+//
+// Improved 3D API (more shippable):
+// #include "stb_rect_pack.h" -- optional, but you really want it
+// stbtt_PackBegin()
+// stbtt_PackSetOversample() -- for improved quality on small fonts
+// stbtt_PackFontRanges() -- pack and renders
+// stbtt_PackEnd()
+// stbtt_GetPackedQuad()
+//
+// "Load" a font file from a memory buffer (you have to keep the buffer loaded)
+// stbtt_InitFont()
+// stbtt_GetFontOffsetForIndex() -- indexing for TTC font collections
+// stbtt_GetNumberOfFonts() -- number of fonts for TTC font collections
+//
+// Render a unicode codepoint to a bitmap
+// stbtt_GetCodepointBitmap() -- allocates and returns a bitmap
+// stbtt_MakeCodepointBitmap() -- renders into bitmap you provide
+// stbtt_GetCodepointBitmapBox() -- how big the bitmap must be
+//
+// Character advance/positioning
+// stbtt_GetCodepointHMetrics()
+// stbtt_GetFontVMetrics()
+// stbtt_GetCodepointKernAdvance()
+//
+// Starting with version 1.06, the rasterizer was replaced with a new,
+// faster and generally-more-precise rasterizer. The new rasterizer more
+// accurately measures pixel coverage for anti-aliasing, except in the case
+// where multiple shapes overlap, in which case it overestimates the AA pixel
+// coverage. Thus, anti-aliasing of intersecting shapes may look wrong. If
+// this turns out to be a problem, you can re-enable the old rasterizer with
+// #define STBTT_RASTERIZER_VERSION 1
+// which will incur about a 15% speed hit.
+//
+// ADDITIONAL DOCUMENTATION
+//
+// Immediately after this block comment are a series of sample programs.
+//
+// After the sample programs is the "header file" section. This section
+// includes documentation for each API function.
+//
+// Some important concepts to understand to use this library:
+//
+// Codepoint
+// Characters are defined by unicode codepoints, e.g. 65 is
+// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is
+// the hiragana for "ma".
+//
+// Glyph
+// A visual character shape (every codepoint is rendered as
+// some glyph)
+//
+// Glyph index
+// A font-specific integer ID representing a glyph
+//
+// Baseline
+// Glyph shapes are defined relative to a baseline, which is the
+// bottom of uppercase characters. Characters extend both above
+// and below the baseline.
+//
+// Current Point
+// As you draw text to the screen, you keep track of a "current point"
+// which is the origin of each character. The current point's vertical
+// position is the baseline. Even "baked fonts" use this model.
+//
+// Vertical Font Metrics
+// The vertical qualities of the font, used to vertically position
+// and space the characters. See docs for stbtt_GetFontVMetrics.
+//
+// Font Size in Pixels or Points
+// The preferred interface for specifying font sizes in stb_truetype
+// is to specify how tall the font's vertical extent should be in pixels.
+// If that sounds good enough, skip the next paragraph.
+//
+// Most font APIs instead use "points", which are a common typographic
+// measurement for describing font size, defined as 72 points per inch.
+// stb_truetype provides a point API for compatibility. However, true
+// "per inch" conventions don't make much sense on computer displays
+// since they different monitors have different number of pixels per
+// inch. For example, Windows traditionally uses a convention that
+// there are 96 pixels per inch, thus making 'inch' measurements have
+// nothing to do with inches, and thus effectively defining a point to
+// be 1.333 pixels. Additionally, the TrueType font data provides
+// an explicit scale factor to scale a given font's glyphs to points,
+// but the author has observed that this scale factor is often wrong
+// for non-commercial fonts, thus making fonts scaled in points
+// according to the TrueType spec incoherently sized in practice.
+//
+// ADVANCED USAGE
+//
+// Quality:
+//
+// - Use the functions with Subpixel at the end to allow your characters
+// to have subpixel positioning. Since the font is anti-aliased, not
+// hinted, this is very import for quality. (This is not possible with
+// baked fonts.)
+//
+// - Kerning is now supported, and if you're supporting subpixel rendering
+// then kerning is worth using to give your text a polished look.
+//
+// Performance:
+//
+// - Convert Unicode codepoints to glyph indexes and operate on the glyphs;
+// if you don't do this, stb_truetype is forced to do the conversion on
+// every call.
+//
+// - There are a lot of memory allocations. We should modify it to take
+// a temp buffer and allocate from the temp buffer (without freeing),
+// should help performance a lot.
+//
+// NOTES
+//
+// The system uses the raw data found in the .ttf file without changing it
+// and without building auxiliary data structures. This is a bit inefficient
+// on little-endian systems (the data is big-endian), but assuming you're
+// caching the bitmaps or glyph shapes this shouldn't be a big deal.
+//
+// It appears to be very hard to programmatically determine what font a
+// given file is in a general way. I provide an API for this, but I don't
+// recommend it.

+ Basic UTF-8 manipulation routines
+ by Jeff Bezanson
+ placed in the public domain Fall 2005
+
+ This code is designed to provide the utilities you need to manipulate
+ UTF-8 as an internal string encoding. These functions do not perform the
+ error checking normally needed when handling UTF-8 data, so if you happen
+ to be from the Unicode Consortium you will want to flay me alive.
+ I do this because error checking can be performed at the boundaries (I/O),
+ with these routines reserved for higher performance on data known to be
+ valid.
+ A UTF-8 validation routine is included.
