     * viewport and see which pixel it ends up in. So far we've seen top left
     * and bottom left conventions. This test may produce unexpected results
     * if the driver forces multisampling on us.
     *
     * If we find a bottom-left filling behavior we also move the x-axis
     * by the same amount. This is necessary to keep diagonals that go
     * through the pixel center intact.
     *
     * Note that we are ignoring some settings that might influence the
     * driver: How we switch GL to an upper-left coordinate system,
     * shaders vs fixed function GL. Testing these isn't possible with
     * the current draw_test_quad() infrastructure. Also the test is
     * skipped if we are not using FBOs. Drawing into the onscreen
     * frame buffer may also yield different driver behavior.
     *
     * The minimum offset also depends on the viewport size, although
     * the relation between those two is GPU dependent and not exactly
     * sensible. E.g. a 8192x8192 viewport on a GeForce 9 needs at
     * least an offset of 1/240.9, whereas a 8x8 one needs 1/255.982;
     * 32x32 needs 1/255.935. 4x4 and lower are happy with something
     * below 1/256. The 8x8 size below has been arbitrarily chosen to
     * get a useful result out of that card and avoid allocating a
     * gigantic texture during library init.
     *
     * Newer cards usually do the right thing anyway. In cases where
     * they do not (e.g. Radeon GPUs in a macbookpro14,3 running MacOS)
     * an offset of 1/2^20 is enough. */
