>Graphite is a technology for rendering complex scripts by reading extra
>tables that are added to Windows TrueType fonts, and WorldPad is a basic
>word processor that uses this technology. There's even a project to make
>a version of Mozilla with Graphite support. They have sample fonts that
>illustrate complex features of scripts like Tamil and Burmese. There's
>an IPA font that can handle contour tones, stacked diacritics,
>diacritics on letters with ascenders and descenders, positioning of the
>superimposed tilde diacritic, etc. I started adding some Graphite
>features to my OlaeUni font; it takes some getting used to, but it's
>pretty powerful once you figure out how it works. I don't think I'll
>have any difficulty adapting the Kazvarad or Neesklaaz fonts. You can
>even add optional features to fonts, so that for instance you could deal
>with ligatures differently in two different languages.
