Sure I can change it. I'm curious though, why the change from the OpenGL spec? There are lots of things I would love to change about OpenGL, why this one in particular?

CC'ing Gregg. Looking at that test, it seems to me it should be split
into two sections, one with valid offsets and one with invalid offsets
verifying that INVALID_OPERATION is generated.
