/**
* This test works by setting up a clip area that equals the visible area

* 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.
