[PATCH] rendercheck: fix a bunch of gradients test

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This takes a rendercheck against master Xephyr using fb from

18731 tests passed of 51681 total
to
49373 tests passed of 51681 total

I'll leave it up to the reader to
a) tell me why?
b) tell me if pixman or rendercheck is wrong.
