From: Ian Romanick <ian.d.roman...@intel.com> If size is small (such as 1),
pitch = ROUND_DOWN_TO(MIN2(size, (1 << 15) - 1), 4); makes pitch = 0. Then height = size / pitch; causes a division-by-zero exception. If pitch is zero, set height to 1 and avoid the division. This fixes piglit's bin/getteximage-formats test and glean's bufferObject test. NOTE: This is a candidate for the 8.0 release branch.
