Description Mark Janes 2016-02-16 19:39:54 UTC
This test began failing with the following output:

/tmp/build_root/m64/lib/piglit/bin/getteximage-formats init-by-clear-and-render -auto -fbo
Using test set: Core formats
The textures will be initialized by rendering to them using glCear and glDrawPixels.
getteximage-formats failure: format: 3, level 1 at pixel(369, 103)
 Expected (0.992157, 0.992157, 0.501961, 1.000000)
	 Found (0.000000, 0.000000, 0.000000, 1.000000)
Tolerance (0.031250, 0.031250, 0.031250, 0.250000)
{many other pixel comparisons follow}

as it didn't regress piglit but instead fixed one newly introduced
test exercising a corner in case in i965 driver. However, saving and
restoring vertex buffer context is complicated and requires more
