Store AA level used to render a glyph in the glyphcache.
In the existing code, glyphs are stored/retrieved from the glyphcache
with no reference to the antialias level used to create them. This
means that if we are using different aa levels in different threads,
we can retrieve 'non-matching' glyphs and hence get rendering
indeterminisms.
Fixed simply here by storing the aa level in the glyphcache too.
