Details:

When doing the following, where you have image "a" and image "b":

[b lockFocus];
[a compositeToPoint: somePoint operation: NSCompositeSourceOver];
[b unlockFocus];

The expected result is that A will be laid in over B, this is not working
properly.   This works on Mac OS X just fine, but doesn't function on
GNUstep.

I will attach an example program that illustrates this issue clearly in the
next couple of days.
