    glamor: Replace CompositeGlyphs code [v2] · b0d2e010
    Keith Packard authored
    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
