	\brief Handler for BBitmap allocation
	
	Whenever a ServerBitmap associated with a client-side BBitmap needs to be 
	created or destroyed, the BitmapManager needs to handle it. It takes care of 
	all memory management related to them.

	NOTE: The allocator used is not thread-safe, it is currently protected
	by the BitmapManager lock.
