Well, I'm not terribly impressed by the Graphics library 1/2 ;-) You
absolutely have to release window DCs you grab via GetDC() to avoid
running out of resources -- this is Petzold-101 stuff. So, to avoid seeing
side-effects of running out of DCs, I suggest you change
GraphicsWND.drawWND to:
drawWND :: WND -> Draw () -> IO ()
drawWND wnd p = do
hwnd <- getHWND wnd
withDC (Just hwnd) (unDraw p)
