	Copy from them GM or watch the new license...

	The compositing code in IM/GM supports all but two of the 
GIMPs layer compositing modes (I know because I added a few when I 
did the XCF support for IM/GM).   There is commented code (or at 
least used to be, haven't looked in a while) for doing the other two 
modes - just never got around to finishing.
