-/* History:
- *
- * 2006-06-13 Paul Giblock reports a "Strange alpha channel problem" on
- * the cairo mailing list.
- *
- * 2006-06-13 Carl Worth writes this test in an attempt to reproduce
- * the problem. The test first fills in a 3x3 rectangle with red, then
- * starts pounding on that center pixel with various forms of
- * zero-alpha rendering to see if its value can ever be made to
- * change.
- *
- * 2006-06-13 Paul Giblock reports that this only happens with the
- * xlib backend, and then only on some systems.
