Class Description

 A Graphical line

 Line default constructor.

 Line normal constructor.

 Line default destructor.

 Line copy constructor.

 Copy this line to line.

 Compute distance from point px,py to a line.

 Draw this line with new coordinates.

 Draw this line with new coordinates in NDC.

 Execute action corresponding to one event.
  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.

 List this line with its attributes.

 Paint this line with its current attributes.

 Draw this line with new coordinates.

 Draw this line with new coordinates in NDC.

 Dump this line with its attributes.

 Save primitive as a C++ statement(s) on output stream out

 Stream an object of class TLine.
