bypass_vs_clip_and_viewport
^^^^^^^^^^^^^^^^^^^^^^^^^^^

+When set, this implies that vertices are pre-transformed for the
+viewport, and will not be run through the vertex shader. Note that
+these vertices will fall outside the conventional unit-cube clip
+space. Implementations are expected to discard pixels which fall
+outside the viewport (XXX: how is the viewport defined in this case),
+and may if desired choose to subject these vertices to clipping after
+appropriate transformation to the clipping cube.
