    test-utils: Use a power-of-two size for the FBO
    
    When testing with COGL_DEBUG=disable-npot-textures all of the tests
    would fail because the testing infrastructure itself ends up creating
    a sliced texture and then trying to use it as a render target. This
    just modifies test-utils to use 512x512 for the size of the texture.
