code: public void frameArc(final Rectangle2D pRectangle, int pStartAngle, int pArcAngle) {
          frameShape(toArc(pRectangle, pStartAngle, pArcAngle, false));
      }
docs: FrameArc(r,int,int) // outline arc with the size, pattern, and pattern mode of
  the graphics pen.
  
  @param pRectangle  the rectangle to frame
  @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)
