Mapping colorop to pixelshader is necessary because misc_state_template
defines a pixel shader handler. We have to use the same representative
in all pipeline parts.

Wined3d_cs_exec_set_texture dirtifies the pixel shader state when the
fixup of a texture changes. Atifs no longer needs a pixel shader handler
on its own since vertex shader updates aren't delayed any more when the
pixel shader state is dirty.
