I didn't find a good way to test the others change ; TEX/VTX is a gpu specific thing (it fetch texture data from video memory)
and are better tested inside an opengl or opencl stack. For this we use piglit (10 000+ opengl tests), for lit test I can only
think of test that would check that clause content is never before a cf_end/cf_nop but such bug are immediately spotted by
piglit (the test would lock your computer).
