\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.
