[MLton] Estimate on difficulty...

[Daniel C. Wang]

I'd like to do the following demo.. basically take the ICFP raytracing 
benchmark and hook it up to a real physical render buffer so I can render 
things interactively with MLTon.

I'd like to do this on Cygwin. Any advice on what's the least painless way 
to do the above. i.e. what simple graphics libs have already been ported to 
MLton.. is there a nice SDL binding already or do I have to do this myself?
The more code I can crib from somone else the happier I'll be. :)
I really just want a raw window with some keyboard and mouse input.
