+/**
+ * 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.
