I find it strange that there are 2 completely different code paths for 
determining card capabilities. So I was thinking to share the code between 
d3d_level_from_gl_info and shader_glsl_get_caps. Since such shared code needs 
to be able to differentiate between d3d 9 with SM 2 and d3d 9 with SM 3 I was 
wondering if it would be a good idea to expose SM info to the current callers 
of d3d_level_from_gl_info to pick Radeon 9500 for SM2 or Radeon X1600 for SM3.

Alternatively I could leave it return 9 as it does now and add an extra 
parameter that will return the shader model. Probably that would be cleaner.
