|
|
* 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.
