[Mono-osx] MonoMac and OpenTK?

So MonoMac will not be exposing the OpenGL bindings from MacOSX but 
instead be integrating OpenTK?  I have not touched MonoTouch in a really 
long time so did not know that is what you guys were using.

I have had a working example of the bindings for OpenGL started on my 
harddrive for a couple of weeks now.  I wanted to write a screen capture 
program and have it working with preliminary bindings.  Basically enough 
to create a screen capture using OpenGL and then saving that image off 
to a .tiff file.  Unfortunately the CGImageDestination class is throwing 
me a curve ball and not working.

If we are waiting on the OpenTK bindings then will hold off on what I am 
doing.  If you are interested in having the beginnings of an OpenGL 
bindings as well let me know.
