Another comment missed from the unsent mail:
These two loops are so similar. The should be refactored into a
separate function that takes the list of targets and the expected error
(GL_NO_ERROR or GL_INVALID_OPERATION) as parameters. I really had to
strain to see what was different between the two loops.
