\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.
