It allows for a variety of rendering rules, including ligatures, glyph substitution, glyph insertion, glyph rearrangement, anchoring diacritics, kerning, and justification. Graphite rules may be sensitive to the context. For instance, there might be a glyph substitution rule that replaces every non-final s by an ſ. In a Graphite font, all smart rendering information resides within the font file. In order to display the Graphite smart rendering, an application needs only Graphite support, but no built-in knowledge about the writing system’s rendering. This makes Graphite especially suited for minority writing systems that cannot rely on applications to provide built-in rendering information. In this regard, Graphite is similar to AAT and different from OpenType which requires applications to provide built-in rendering information. Graphite supportGraphite was originally implemented on Windows. It has been ported to Linux. It is also available on Mac OS X Snow Leopard[3] although with AAT, Mac already provides a technology suitable for minority scripts. Applications that support Graphite include the SIL WorldPad,[4] XeTeX, OpenOffice.org (since version 3.2, except for the macOS version), LibreOffice (formerly except for the macOS version, since version 5.3 become availably on all platforms[5]). It was built into Thunderbird 11 and Firefox 11,[6] and was turned on by default since version 22, but was disabled with version 45.0.1 and re-enabled with version 49.0.[7][8] Graphite support can be added to applications on Linux with the package pango-graphite[9] and on Windows with the experimental add-on MultiScribe.[10] See also{{Portal|Free and open-source software}}
