> Patch V0

Hi,

I wrote a patch for this. This patch makes WebKit possible to render UVSes in MacOS10.6. Here are some notes:
- For win port with CoreGraphics wrapper, I tried to use wkGetGlyphs() to obtain glyph id for UVSes, but it seems that it doesn't support UVSes even on Windows7, which supports UVSes. Since I cannot see the code and cannot modify it, I think we should wait for updating the library function by Apple.
- Other ports are not supported for now. Once I can successfully add UVSes support on MacOS10.6, I'd like to continue to implement on another ports which provide a way to handle UVSes (e.g. ports using FreeType2).
- For a test, I used a tiny TrueType font which is used by Mozilla <http://mxr.mozilla.org/mozilla-central/source/layout/reftests/fonts/gw432047.ttf>. It's originally from <http://en.glyphwiki.org/> and can be used in public (See the license: http://en.glyphwiki.org/wiki/GlyphWiki:License).
