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.

What's the license on this test case? Can we include it in mauve?
Fixed by Sven de Marothy in GNU Classpath. Closing.
