Also, expand out pixels in lines, it's just too slow otherwise (30%
overhead or so.)

This way it can be applied to other primitives. But, this will probably
need larger changes to implement mipmapping.

Nearest is much faster, so you can force it to nearest for a good boost in
speed.

Dividing by 256 gives us a range of 0-253, and incorrectly gets zero for
some components (guessing alpha, primarily?) in some games.
Dividing by 255 has a speed hit, so a slight bias to the top left seems
like a decent performance compromise (and it's a very slight bias.)
