The actual interesting failure here is attempting a readpixels from a
huge depth FBO in the process of doing copypixels, which fails by using
GTT mapping when it's not possible.  The risk with the testcase as-is is
that we might change the copypixels path to just bind the FBO as a
texture and render with it, which would paper over the issue.

Could you switch it to just make a huge FBO, initialize it, and try to
read it?
