class TCurlyArc: public TCurlyLine

 Default constructor

 create a new TCurlyarc with center (x1, y1) and radius rad.
 The wavelength and amplitude are given in percent of the line length
 phimin and phimax are given in degrees.

 Create a curly (Gluon) or wavy (Gamma) arc.

 Compute distance from point px,py to an arc.

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

 Execute action corresponding to one event.

  This member function is called when a TCurlyArc 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.

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