The rounding used when storing 10-bit per component data into an 8-bit per component texture seems to have changed in recent versions of Mesa which was causing this test to fail. I've also noticed this failing on the NVidia binary driver. This patch adds some fuzziness to the comparison so that it will pass. There is a new test_utils function called test_utils_compare_pixel_and_alpha which is the same as test_utils_compare_pixel except that it also compares the alpha component.
