15	* TODO: Not thread/process safe
16	*
17	* NOTE: To access a window object, you must call GetWindowFromOS2Handle or
18	* GetWindowFromHandle. Both these methods increase the reference count
19	* of the object. When you're done with the object, you MUST call
20	* the release method!
21	* This mechanism prevents premature destruction of objects when there
22	* are still clients using it.
23	*
24	* NOTE: Client rectangle always relative to frame window
25	* Window rectangle in parent coordinates (relative to parent's client window)
26	* (screen coord. if no parent)
27	*
28	* NOTE: Status of window:
29	* Before a window has processed WM_NCCREATE:
30	* - GetTopWindow can't return that window handle
31	* - GetWindow(parent, GW_CHILD) can't return that window handle
32	* - IsChild works
33	* TODO: Does this affect more functions?? (other GetWindow ops)
