When the OpenGL-based pipeline is enabled, scaled image copies produce
incorrect results when any of the source parameters fall outside the bounds
of the source image. For instance, suppose you have a 100x100 image, and you
call:
    g.drawImage(img, 0, 0, 100, 100, 0, 0, 200, 200);
The last two source parameters in this case (200,200) are obviously outside
the bounds of the source image. The OGL-based pipeline does not deal with
this case properly.

You can see this problem clearly by compiling and running the attached testcase
while specifying the -Dsun.java2d.opengl=True flag. Note that the first
testcase (first row, second column) behaves differently than when the OGL flag
is not specified (the correct behavior).
