Class Description

 A diamond is defined by :
   - Its central left coordinates x1,y1
   - Its top central coordinates x2,y2

 A diamond has line attributes (see TAttLine)
   and fill area attributes (see TAttFill).

 Like for the class TPaveText, a TDiamond may have one or more line(s)
 of text inside.

Int_t DistancetoPrimitive(Int_t px, Int_t py)
*-*-*-*-*-*-*-*-*Compute distance from point px,py to a diamond*-*-*-*-*-*
*-*              ==============================================
  Compute the closest distance of approach from point px,py to the
  edges of this diamond.
  The distance is computed in pixels units.


void Draw(Option_t *option)
*-*-*-*-*-*-*-*-*-*-*Draw this diamond with its current attributes*-*-*-*-*-*

  This member function is called when a Diamond object is clicked.

  If the mouse is clicked inside the diamond, the diamond is moved.

  If the mouse is clicked on the 4 tops (pL,pR,pTop,pBot), the diamond is rscaled.
