[Mesa-dev] [PATCH] gallium/tests/trivial: fix viewport depth transform

[Ilia Mirkin]

These were getting mapped off into outer space, which would cause nv50
and nvc0 to clip the primitives (as depth_clip was enabled).

Oddly enough, it worked with nv30 and llvmpipe though. Perhaps their
frustrum clipping rules are a bit different?
