I can't speak towards the bitfield part, but implementing vertex
blending in software will magically make a few games (two that I know
of, Warhammer Online and Everquest) work without patching, and without
passing through drawStridedSlow.

This is because they don't actually use the vertex blending, but produce
unrecognised (by Wine) vertex data if the capability isn't there.

Of course Pacman didn't influence us as kids. If it did,
we'd be running around in darkened rooms, popping pills and
listening to repetitive music.
