--- Comment #9 from Ian Romanick <idr at freedesktop.org> ---
All the DIFFERING_SIGN business is just a red herring, and this isn't a real
regression.  It was just dumb luck that vs-clip-vertex-const-reject.shader_test
ever passed.  I tried several of the other vs-clip-vertex-* tests pass.  None
of them pass because the clip code always uses gl_Position for clipping instead
of gl_ClipVertex.

I'm removing this from the blocker list and updating the summary.
