Add some stats to get some idea of much alpha tested drawing we do.

Turns out it's one hell of a lot and we really should fix this by
checking both vertices and textures to deduce when we can just skip
alpha testing safely, probably quite often.

I care about this because alpha testing drawing is very expensive
on some mobile chips.
