I wish to implement something functionally like the icons
on the Finders desktop, and I am currently doing it this
way:

    - traversing the list of windows, subtracting each visible
      window's rectangle from the icon rectangles region
      
    - Use this new region as the clip region
    
    - and then drawing the icon on the desk port.

and I do this for each icon.

Does anybody know of a better way to implement such functionality?
