	\brief BView/BWindow combination graphics module

	First, slowest, and easiest driver class in the app_server which is designed
	to utilize the BeOS graphics functions to cut out a lot of junk in getting the
	drawing infrastructure in this server.
	
	The concept is to have VDView::Draw() draw a bitmap, which is a "frame buffer" 
	of sorts, utilize a second view to write to it. This cuts out
	the most problems with having a crapload of code to get just right without
	having to write a bunch of unit tests
	
	Components:		3 classes, VDView, VDWindow, and ViewDriver
	
	ViewDriver - a wrapper class which mostly posts messages to the VDWindow
	VDWindow - does most of the work.
	VDView - doesn't do all that much except display the rendered bitmap
