* This test verifies that expected GL errors are produced for cases mentioned
* in EXT_framebuffer_multisample_blit_scaled extension:
*
* "If the draw framebuffer is framebuffer complete and has a value of
* SAMPLE_BUFFERS that is greater than zero, or if the read framebuffer
* is framebuffer complete and has a value of SAMPLE_BUFFERS that is
* zero, then the error INVALID_OPERATION is generated if BlitFramebuffer
* is called and the filter is SCALED_RESOLVE_FASTEST_EXT or
* SCALED_RESOLVE_NICEST_EXT."
