This can be derived from the shader caps.
All GPUs from ATI/AMD, NVIDIA, and INTEL have separate texture slots
for each shader stage.

* ``PIPE_CAP_MAX_STREAM_OUTPUT_BUFFERS``: The maximum number of stream buffers.
* ``PIPE_CAP_PRIMITIVE_RESTART``: Whether primitive restart is supported.
-* ``PIPE_CAP_MAX_COMBINED_SAMPLERS``: The total number of samplers accessible from
- the vertex and fragment shader, inclusive.
* ``PIPE_CAP_INDEP_BLEND_ENABLE``: Whether per-rendertarget blend enabling and channel
masks are supported. If 0, then the first rendertarget's blend mask is
replicated across all MRTs.
