It even uses c255, actually. How exactly is this not a typical case of running
out of available uniforms? Any shader that uses indirect addressing potentially
uses all 256 uniforms, and wined3d needs a few for internal use. If your
graphics card doesn't have that many, and the shader actually uses those higher
constants, you're currently simply out of luck.
