Create an FBO with two color attachments: one integer, the other

Also, test the value of querying GL_RGBA_INTEGER_MODE_EXT. It should
be true whenever at least one attachment is integer.
NOTE: This test fails with both NVIDIA and llvmpipe. It seems that no
matter whether the second attachment is integer or unorm, the rendering
doesn't work. I don't know if this is a driver bug, undefined behavior
or if I've got something wrong in my code. Ideas appreciated.
This test also fails on Intel.
Thanks for testing. I'm _pretty_ sure my code is correct but maybe
someone could double-check my work. I'd have thought that there's
probably some app out there that might try to do this, and that it
should work.
