My question *is* about the protocol.

Let me try again: to a client, after it sends a scale of a 100x100 
buffer to 200x200, is there any indication of that original 100x100 size 
in any protocol events or requests afterwards, or does it work precisely 
the same as though they sent an unscaled 200x200 buffer?
