* @ 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 .
