S.W.F = System.Windows.Forms
S.D = System.Drawing

To port to a new toolkit (e.g. Cocoa), you need to build an assembly called 
"System.Drawing.Cocoa", patterned on the existing "System.Drawing.Xsharp" and 
"System.Drawing.Win32" assemblies.

Basically, you need to provide an implementation of "IToolkit", which in turn 
creates instances of "ITookitWindow", "IToolkitGraphics", etc.  Each of these 
will use some mechanism (e.g. PInvoke) to call through to the underlying OS 
drawing libraries.

The new toolkit assembly should be hooked into System.Drawing by editing the 
"CreateDefaultToolkit()" method.  For testing, you can now set the 
PNET_WINFORMS_TOOLKIT environment variable to "Foo" and it will load 
"System.Drawing.Foo".  You can also use "ilrun blah.exe --toolkit=Foo" if you 
don't want to modify the environment.
