This looks like a difficult problem to fix.  I also looked for a better
way to fix the problem, but I gave up after concluding that any
thoroughly correct fix seemed to require endless yak shaving.

If this fixes dEQP regressions, without regressing other things, then
I approve the patch. But, I'm not convinced yet that it doesn't regress
X11 pixmaps. I want to run some tests and step through the code with gdb
before I give a reviewed-by.
