Under MS Windows 3.1, this can be done -- it is used by the
GhostScript/GhostView combination to provide a nicer user interface under
Windows 3.1 than the raw GhostScript interface. From examining the Win32
API help file, it looks like this method should work under NT and Chicago
also. It should be noted that only USER objects are global (window handles
et. al.); GDI handles are private to each task.
