There's quite a bit of functionality that isn't implemented, or isn't
implemented correctly, in particular v2 and v3 shaders. It also looks
like in certain places code for vertex shaders was simply used for
pixel shaders despite the fact that it's not always possible. There's
probably a fair amount of bugs as well. A lot of that just takes a lot
of time to figure out, but some of it would also require GLSL to
implement correctly.
