* Verify that an FBO with an incomplete texture attached is complete
*
* This test uses a cube map where one of the faces has not been specified.
* As long as the missing face isn't attached to the FBO, the FBO should not
* be incomplete. This test originally wanted the FBO to be incomplete.
* However, this just verified incorrect behavior in another vendor's driver.
