3187e7b978SAxel Dörfler/*!	A word about memory housekeeping and why it's implemented this way:
3237b502f2SAxel Dörfler
3337b502f2SAxel Dörfler	The reason why this looks so complicated is to optimize the most common
3437b502f2SAxel Dörfler	path (bitmap creation from the application), and don't cause any further
3537b502f2SAxel Dörfler	memory allocations for maintaining memory in that case.
3663c07622SAxel Dörfler	If a bitmap was allocated this way, both, the fAllocator and
3763c07622SAxel Dörfler	fAllocationCookie members are used.
3837b502f2SAxel Dörfler
3921c8c925SAxel Dörfler	For overlays, the allocator only allocates a small piece of client memory
4021c8c925SAxel Dörfler	for use with the overlay_client_data structure - the actual buffer will be
4121c8c925SAxel Dörfler	placed in the graphics frame buffer and is allocated by the graphics driver.
4237b502f2SAxel Dörfler
4337b502f2SAxel Dörfler	If the memory was allocated on the app_server heap, neither fAllocator, nor
4437b502f2SAxel Dörfler	fAllocationCookie are used, and the buffer is just freed in that case when
4537b502f2SAxel Dörfler	the bitmap is destructed. This method is mainly used for cursors.
