* This file contains routines to support MDI (Multiple Document

* Notes: Fairly complete implementation. Any volunteers for
* "More windows..." stuff?
*
* Notes: Fairly complete implementation.
* Also, Excel and WinWord do _not_ use MDI so if you're trying
* to fix them look elsewhere.
*
* Notes on how the "More Windows..." is implemented:
*
* When we have more than 9 opened windows, a "More Windows..."
* option appears in the "Windows" menu. Each child window has
* a WND* associated with it, accesible via the children list of
* the parent window. This WND* has a wIDmenu member, which reflects
* the position of the child in the window list. For example, with
* 9 child windows, we could have the following pattern:
*
*
*
* Name of the child window pWndChild->wIDmenu
* Doc1 5000
* Doc2 5001
* Doc3 5002
* Doc4 5003
* Doc5 5004
* Doc6 5005
* Doc7 5006
* Doc8 5007
* Doc9 5008
*
*
* The "Windows" menu, as the "More windows..." dialog, are constructed
* in this order. If we add a child, we would have the following list:
*
*
* Name of the child window pWndChild->wIDmenu
* Doc1 5000
* Doc2 5001
* Doc3 5002
* Doc4 5003
* Doc5 5004
* Doc6 5005
* Doc7 5006
* Doc8 5007
* Doc9 5008
* Doc10 5009
*
* But only 5000 to 5008 would be displayed in the "Windows" menu. We want
* the last created child to be in the menu, so we swap the last child with
* the 9th... Doc9 will be accessible via the "More Windows..." option.
*
* Doc1 5000
* Doc2 5001
* Doc3 5002
* Doc4 5003
* Doc5 5004
* Doc6 5005
* Doc7 5006
* Doc8 5007
* Doc9 5009
* Doc10 5008
