It is not so simple.
1) msdn does not make it clear whether that's visible on the app side
2) msdn claims constants take effect on Set*Shader*, whereas ours do on draw
A test is really needed if this is to be fixed - I tried to write one,
but d3d8 wouldn't accept my asm shader for some reason.... and I can't
find d3d8 documentation online which really makes me not very interested
in writing d3d8 patches.
===========
Anyway, I think that bringing constants out of the shader is a step in
the right direction, fixing issues like this should be easier afterwards.
