Can you add comments to explain the steps this test is doing and why? Such as
"This quad uses the first shared quad state". "The next 3 quads use the second
shared quad state". etc.. It really helps understand a test for readers to have
these types of comment, since they tend to be walls of code and the intent gets
lost.
