{
float w = (float)canvas.ToUnit(20); // include space for the 'extern' nodes
rect.Inflate(w, w);
}

// if drawing either angle then include the mouse point in the rectangle - this is to redraw (erase) the line drawn
// from center point to mouse point
//if (m_curPoint == eCurrentPoint.startAngle || m_curPoint == eCurrentPoint.endAngle)
