 * @author cheth

 * @summary verifies that drawImage behaves the bounds of a complex

 * clip shape.  This was a problem with our GDI renderer on Windows, where

 * we would ignore the window insets.

 * @run main InsetClipping

*/

/**

 * 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.
