Clay Fowler was able to provide more information about the drawing
bridge (appended to the end of this message). The good news is that
the functionality is already built into MonoMac using
Graphics.fromHwnd(). The bad news is that it depends on the user
having X11 installed, as well as a version of libfreetype.6.dylib
which is newer than the one included with Apple's X11.
Hope that helps,
