Sorry, I forgot to reply to that last part.  CGLSetSurface is one of 
the more important undocumented functions for attaching a context to a 
window, but that's not what I use in the render spu; well, not directly 
at least :)

In the render spu, I'm using AGL to do all of the drawing and whatnot, 
which includes using aglSetDrawable to attach a context to a 
window/drawable.  This isnt the linking I mentioned, though.  What I 
was referring to was using the window's "RefCon" to store which context 
that window is using.  This is used later in the other functions that 
need the context, but only have the window.  It's a little trick I 
found in the sample programs that Apple has :)

I am thinking of doing this in the fakerlib, but I am not sure if it 
would be ok to do this in there.  I am looking into this right now.
