New composite glyphs code uses the updated glamor program infrastructure to create efficient shaders for drawing render text. Glyphs are cached in two atlases (one 8-bit, one 32-bit) in a simple linear fashion. When the atlas fills, it is discarded and a new one constructed. v2: Eric Anholt changed the non-GLSL 130 path to use quads instead of two triangles for a significant performance improvement on hardware with quads. Someone can fix the GLES quads emulation if they want to make it faster there. v3: Eric found more dead code to delete Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Eric Anholt <eric@anholt.net>
