This will only work if the shader samples 2D textures, or is a 1.x pixel 
shader.

I am afraid you'll have to add bit for no texture being bound to a sampled 
sampler to the ps_compile_args structure and replace the TEX statement with 
reading a constant instead. Or explicitly bind dummy 2D, 3D, Cube and RECT 
textures to unused samplers. (and e.g. a dummy 2D, 3D and RECT sampler if a 
volume texture is used)
