uniformf.html etc. require exact pixel values
Last modified: 2011-05-09 03:35:11 PDT
Several testcases, starting with uniformf.html, set a uniform value in a shader and then read out the pixels with readPixels(), and conclude with a comparison of pixel values. This comparison requires that the pixel values be exactly as expected, rather than allowing for some amount of error. Most other test cases have an allowable error range when checking pixel values.
