	\class ServerWindow ServerWindow.h
	\brief Shadow BWindow class
	
	A ServerWindow handles all the intraserver tasks required of it by its BWindow. There are 
	too many tasks to list as being done by them, but they include handling View transactions, 
	coordinating and linking a window's WinBorder half with its messaging half, dispatching 
	mouse and key events from the server to its window, and other such things.
