767 single read and write of each texel. The skeleton of these tests is as follows:
770 texel, where the read is in the fragment shader invocation that writes
771 the same texel, works as expected. Use the following fragment shader as
822 texel(m_reference[i], x, y)++;
836 Test case #3: Single read and write of the same texel
839 texel, where the read is in the fragment shader invocation that writes
840 the same texel, works as expected.
848 "Using the basic outline tests that a single read and write of each texel, where the read "
849 "is in the fragment shader invocation that writes the same texel, works as expected.")
865 /* A single read and write of the same texel doesn't require a texture barrier. */
873 Test case #4: Multipass read and write of the same texel (with texture barrier)
876 texel, where the read is in the fragment shader invocation that writes
877 the same texel, works as expected.
889 "Using the basic outline tests that multiple reads and writes of each texel, where the read "
