Um. So, yeah. Two massive WTF moments here. The first one is that, somehow,
I never actually hooked up vertex shader emission, so the only time that the
VAP gets set up is during surface_copy/surface_fill. That's why acidgears
was happening.

The second one is that, somehow, once I actually hooked it up, glxgears just
magically worked. Without any actual, real testing, I somehow accidentally
made the shader compiler work. Go figure.
