glx: Test behavior of glXQueryDrawable()

Add the following tests:

* glx-query-drawable-GLXBadDrawable
      Calls glXQueryDrawable(draw=0) and expects that the GLXBadDrawable
      error is generated.

* glx-query-drawalbe-GLX_WIDTH
* glx-query-drawalbe-GLX_HEIGHT
      Calls glXQueryDrawable() with the given attribute.

Tested on Fedora 15 with Xserver 1.10.14. With the proprietary Nvidia
driver, all tests pass. With Mesa 7.11, the GLXBadDrawable test passes but
the other two fail.

All tests fail on Fedora 16.
All tests pass, however, with the proprietary Nvidia driver on Fedora 15.
