      The font engine on Mac uses unhinted glyphs and thus permits subpixel positioning of the glyphs using cleartype rendering to express coverage of a pixel.

      Implement support for this in the raster paint engine by maintaining three different glyph caches, one for each subpixel position (0, 1/3, and 2/3 of the pixel is covered.)
