AcGiDrawableOverrule overrules a subset of draw related operations that the AcGiDrawable class specifies. It is intended as a base class for clients who want to alter some or all behavior of a given AcGiDrawable-derived class. At the base level, each default implementation simply calls the corresponding method in the target class.
