Class Description

  Different arrow formats as explained in TArrow::TArrow or in
  the picture below are provided.
  Once an arrow is drawn on the screen:
    - One can click on one of the edges and move this edge.
    - One can click on any other arrow part to move the entire arrow.

*-*-*-*-*-*-*-*-*-*-*arrow normal constructor*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ========================
 Define an arrow between points x1,y1 and x2,y2
 the arrowsize is in percentage of the pad height
 Opening angle between the two sides of the arrow is fAngle (60 degrees)

  option = ">"      -------->
  option = "|->"    |------->
  option = "<"      <--------
  option = "<-|"    <-------|
  option = "->-"    ---->----
  option = "-<-"    ----<----
  option = "-|>-"   ---|>----
  option = "<>"     <------->
  option = "<|>"    <|-----|>  arrow defined by a triangle

  Note:
  - If FillColor == 0 draw open triangle else  draw full triangle with fillcolor
    default is filled with LineColor
  - "Begin" and "end" bars can be combined with any other options.
