INTEGRATION: CWS cowfixes01 (1.8.12); FILE MERGED

2006/03/21 13:36:25 thb 1.8.12.3: #i63310# Removed silly self-referentiality for the static default objects (causing infinite loops)
2006/03/17 23:16:34 thb 1.8.12.2: #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)
2006/03/17 17:41:31 thb 1.8.12.1: #i63310# Added COW to B2DMultiRange (wasn't there before); moved BxDHomMatrix to cow_wrapper; added o3tl build dependency
