+	\class BitmapDriver BitmapDriver.h
+	\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.
