The shell32.dll DDE callback isn't always initialized & handling Progman
calls for all apps. I've seen Progman calls pass through the DDE_client
and DDE_server of user32.dll instead and never go through shell32.dll.

We can have the actual Progman functions in shell32.dll, but at least
user32.dll will have to be able to call & be called by these. I think a
separate progman.c/progman.h in /dlls/user32 to handle calls from all
locations may be preferred. Any suggestions?
