| /** |
| * This test works by setting up a clip area that equals the visible area |
| * of the Frame. When we perform any rendering operation to that window, |
| * we should not see the results of the operation because they should be |
| * clipped out. We create an Image with one color (red) and use a |
| * different background fill color (blue). We fill the area with the |
| * background color, then set the clip, then draw the image; if we detect |
| * the image color at pixel (0, 0) then we did not clip correctly and the |
| * test fails. |
