It lets you hook 'pixel callback' functions. Procedural shaders,
basically. It does have this neat concept of a PaintedSet which is
basically an opaqe handle to a region descriptor. Berlin guys should be
able to make good use of this stuff if they wanted to write up a LibXMI
DrawingKit....

I think LibXMI has a lot of potential. Not much has been done
with the potential of the architecture however, much like GGI in some
ways. This will be a real learning experience for sure....
