/**
* The MDI client window manages a number of MDI child windows in a multiple-document
* interface (MDI) application. MDI child windows usually receive messages from the GUI controls
* by delegation via the MDI client. This is accomplished by making the MDI client window
* the target for most GUI controls. The MDI client filters out messages intented for itself,
* and delegates the remaining messages to its currently active MDI child, if any.
* If you use the auto-gray or auto-hide feature available in some GUI controls, these
* controls can be automatically grayed out or hidden when there is no active MDI child.
* When delegating messages via MDI client to MDI child windows of different types, care
* should be taken that message ID's do not overlap, so that all message ID's only map to
* the intented handlers no matter which MDI child window type is active.
* The MDI client sends a SEL_CHANGED message to its target when the active MDI child is
* switched, with the void* pointer refering to the new MDI child.
* A MDI Window selection dialog can be brought up through the ID_MDI_OVER_X messages;
* a menu button connected to the MDI client with the ID_MDI_OVER_X message will be
* automatically grayed out if there are less than X MDI child windows.
