I think you can inline the impl here, as we did for setStrokeParams

+
     /**
      *  Returns true if this specifes any thick stroking, i.e. applyToPath()
      *  will return true.
      */
     bool needToApply() const {
         Style style = this->getStyle();
         return (kStroke_Style == style) || (kStrokeAndFill_Style == style);
     }
