948508 - Make it possible to not use SkFontHost_cairo.cpp on mobile

Status: NEW

(Core :: Graphics, defect)

Description

[Jeff Muizelaar [:jrmuizel]]

We have a couple of different possible approaches here:
1. Expose some of the freetype guts outside of Skia so we can reuse some of the gfxFont freetype stuff.
2. make a gfxFontSkia that only uses the skia apis.

At first I was leaning toward 1 but after some thinking 2 might make more sense. It's probably closer to what we want in the long term, however it may be more work up front depending on how well the skia font host/typeface maps to gfxFont etc.
