code: public void paintArc(final Rectangle2D pRectangle, int pStartAngle, int pArcAngle) {
          paintShape(toArc(pRectangle, pStartAngle, pArcAngle, true));
      }
docs: PaintArc(r,int,int) // fills an arc's interior with the pattern of the
  graphics pen, using the pattern mode of the graphics pen.
  
  @param pRectangle  the rectangle to paint
  @param pStartAngle start angle in degrees (starting from 12'o clock, this differs from Java)
  @param pArcAngle   rotation angle in degrees (starting from {@code pStartAngle}, this differs from Java arcs)
