Author: David_McClarnon (Xara Group Ltd) <*****@*****.**>
Created: 24/2/2000
Inputs: The render region to get the attribute map from
Outputs: An attribute map (copied) from the render region
Returns: -
Purpose: Makes an attribute out of the render region's current attribute state
Notes: You MUST call DeleteAttributes afterwards to release memory - delete is
not sufficient
