* ``PIPE_CAP_QUADS_FOLLOW_PROVOKING_VERTEX_CONVENTION``: Whether quads adhere to
the flatshade_first setting in ``pipe_rasterizer_state``.
* ``PIPE_CAP_USER_VERTEX_BUFFERS``: Whether the driver supports user vertex
buffers. If not, the state tracker must upload all data which is not in hw
resources.
* ``PIPE_CAP_VERTEX_BUFFER_OFFSET_4BYTE_ALIGNED_ONLY``: This CAP describes a hw
limitation. If true, pipe_vertex_buffer::buffer_offset must always be aligned
to 4. If false, there are no restrictions on the offset.
* ``PIPE_CAP_VERTEX_BUFFER_STRIDE_4BYTE_ALIGNED_ONLY``: This CAP describes a hw
limitation. If true, pipe_vertex_buffer::stride must always be aligned to 4.
If false, there are no restrictions on the stride.
* ``PIPE_CAP_VERTEX_ELEMENT_SRC_OFFSET_4BYTE_ALIGNED_ONLY``: This CAP describes
a hw limitation. If true, pipe_vertex_element::src_offset must always be
aligned to 4. If false, there are no restrictions on src_offset.
