[cairo] drawing to desktop

[Travis Griggs]

I've got bindings in Smalltalk for drawing with Cairo to windows or  
pixmaps on X/OSX/Win32. I'd like to toy with drawing straight to the  
desktop. Is this doable? I think I know how to get an HDC for the  
Screen in Win32. But no clue how to do the equivalent in X or OSX.  
Anyone done this and have any (pseudo)code to share?

Time and Countertops. They both get used up way too fast.
