	\brief Driver to draw on ServerBitmaps
	
	This driver is not technically a regular DisplayDriver subclass. BitmapDriver 
	objects are intended for use when a BBitmap is created with the ability to 
	accept child views. It also adds one significant function over regular DisplayDriver 
	child classes - SetTarget. There is also no option for input server emulation, for 
	obvious reasons. Cursor functions are redefined to do absolutely nothing
	
	Usage: Allocate and call SetTarget on the desired ServerBitmap and start calling 
	graphics methods. All ServerBitmap memory belongs to the BitmapManager.
