Class Description

*-*-*-*-*-*-*-*-*-*-*-*-*-*-*Ellipse class*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                          =============
  Ellipse is a general ellipse that can be truncated and rotated.
  An Ellipse is defined by its center (x1,y1) and two radius r1 and r2.
  A minimum and maximum angle may be specified (phimin, phimax).
  The Ellipse may be rotated with an angle theta.
  The attributes of the outline line are given via TAttLine.
  The attributes of the fill area are given via TAttFill.
  The picture below illustrates different types of ellipses.

  Compute the closest distance of approach from point px,py to this ellipse.
  The distance is computed in pixels units.

  This member function is called when a line is clicked with the locator

  If Left button clicked on one of the line end points, this point
     follows the cursor until button is released.

  if Middle button clicked, the line is moved parallel to itself
     until the button is released.
