Does this test pass on any of the closed-source drivers?  Since it uses 
floating-point depth textures, I assume it doesn't pass on Mesa yet.

I have some tests outstanding that put things in tests/spec/gl-3.0/api. 
  I think this test should go in tests/spec/gl-3.0/fbo or 
tests/spec/gl-3.0/texture.  I assume we'll have a similar test that 
tries to create FBOs in all of the required format combinations.

Is this copy-and-pasted from another test?  Since the real test happesn 
in piglit_init, it seems like this should be the usual 'return 
PIGLIT_FAIL;' version of piglit_display.

                 printf("profit");

Sorry, I couldn't resist.
