2006/03/21 13:36:26 thb 1.10.20.2: #i63310# Removed silly self-referentiality for the static default objects (causing infinite loops)
2006/03/17 23:16:35 thb 1.10.20.1: #i63310# Moved BxD(Poly)Polygon to cow_wrapper; added makeUnique() to all classes using COW internally (to at least facilitate deliberate unsharing in multi-threaded uses)
