All DrawingLayer Atrributes used for ptimitives need a default constructor. Since the o3tl::cow_wrapper is used in combination with a static default incarnation of the impl class it is better to define that. Also needed is a working isDefault() implementation that compares the impl class to the static default. Added missing stuff for this.
