No. If I've asked for a white glyph, then it makes sense for that font 
to be rendered in white in as many cases as possible. This patch alters 
that behaviour.

However, it currently does this at the cost of legibility with small 
font sizes. There's an argument for correcting shape by moving away from 
aligning glyphs to pixel boundaries, but it's not an argument we should 
be having this close to release.
