 * CPolyline::Draw
 *
 * Purpose:
 *  Paints the current line in the polyline window.
 *
 * Parameters:
 *  hDC             HDC to draw on, a metafile or printer DC.
 *  fMetafile       BOOL indicating if hDC is a metafile or not,
 *                  so we can avoid operations that RIP.
 *  fEntire         BOOL indicating if we should draw the entire
 *                  figure or not.
 *  pRect           LPRECT defining the bounds in which to draw.
 *
 * Return Value:
 *  None
