image compositor: Support subpixel positioning
Support subpixel positioning with a 4x4 subpixel grid.
When compositing glyphs in the image compositor,
we store the subpixel phases in the high bits of the
glyph index. The _cairo_scaled_glyph_index() macro
has been updated to discard these bits. By storing
the phases in the glyph index, the glyph cache just
keeps working. When loading a glyph, the Freetype
font backend shifts the outline according to the
phases.
