[Bug AWT/17060] New: AWT: problems with drawImage and transparent images

["hendrich at informatik dot uni-hamburg dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The attached testcase demonstrates incorrect handling of transparent 
images in AWT/GtK.

1. The upper button demonstrates that loading and drawing a transparent image
   almost works. However, while the background color is respected, the red
   line should not be overdrawn by the image.

2. In the second button, libgcj incorrectly uses the (default Gtk)
   background color instead of the expected background.
