A reference to the transform object to be unloaded from memory.
DESCRIPTION
The GXUnloadTransform function moves a transform object from the active graphics client heap to disk storage. When you or QuickDraw GX use the GXUnloadTransform function to unload a transform object from memory to disk storage, QuickDraw GX stores its location in a 4-byte stub in the active graphics client heap. When you use the GXLoadTransform function to reload the object from disk storage to memory, QuickDraw GX uses the stub to find the stored transform object.
