Cool.

I just added this change to Morph.slate.  Unfortunately it might be 
several weeks before my patches will be ready; I've been really busy lately.

Here's a quick summary of what I'm working on:

1. Yet another SDL adaptor.  This one bitblts from a Form (the bits are 
in the GC heap!) (working).  It also translates events into the UI Event 
hierarchy and sends them to morphs (also working).  It doesn't rely on 
any of the various SDL extension libraries because all of them look 
pathetic to me.  I still have some cleanup to do, but I've tested it 
under both Linux and Windows.

2. A Cairo port (really nice graphics).  It draws directly on Forms in 
the GC heap.  Unfortunately I had to resort to a nasty hack because the 
GC can't lock objects in memory inbetween calls to external libraries.  
This was working a couple hours ago but I managed to mess it up while 
refactoring.  I haven't tested it under Linux yet.

3. Morph additions to support windows and Cairo.
