The cap means D3DFVF_XYZRHW vertices will see clipping.
This is not the case when
PIPE_CAP_TGSI_VS_WINDOW_SPACE_POSITION is supported, since
it'll disable clipping.

Why is this commented out and not just removed?
In adapter9, we write all possible flags, but comment thoses that we
don't support.

Just to confirm, when that cap is available, you *always* turn use the
window space position?
D3DPMISCCAPS_CLIPTLVERTS indicatesthe device will clip
D3DFVF_XYZRHW vertices. This is what happen with our
fallback of D3DFVF_XYZRHW.
When we have PIPE_CAP_TGSI_VS_WINDOW_SPACE_POSITION, we use
the vs_window_space_position flag to implement D3DFVF_XYZRHW.
According to spec, vs_window_space_position will bypass clipping
too.
