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.
