Incremental Font Transfer Demo
This demonstrates the use of the incremental font transfer (IFT) to load font data for display of a variety of scripts. IFT works by using patches to extend a font to cover more codepoints and/or axes as they are encountered in rendered text. This allows loading of only the parts of a font that are actually needed. This demo is using a fully static (ie. no dynamic backend) version of IFT. IFT is currently in development with the w3c webfonts working group and an early draft of the specification implemented by this demo can be found here.
