Class Description

 Manages Markers. Marker attributes are managed by TAttMarker.
 The list of standard ROOT markers is shown in this picture

~TMarker()
*-*-*-*-*-*-*-*-*-*-*Marker default destructor*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  =========================

TMarker(const TMarker &marker)

void Copy(TObject &obj)
*-*-*-*-*-*-*-*-*-*-*Copy this marker to marker*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ==========================

void DisplayMarkerTypes()
*-*-*-*-*-*-*-*-*-*-*Display the table of markers with their numbers*-*-*-*
*-*                  ===============================================

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


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

void DrawMarker(Double_t x, Double_t y)
*-*-*-*-*-*-*-*-*-*-*Draw this marker with new coordinates*-*-*-*-*-*-*-*-*-*

void ExecuteEvent(Int_t event, Int_t px, Int_t py)
*-*-*-*-*-*-*-*-*-*-*Execute action corresponding to one event*-*-*-*
*-*                  =========================================
  This member function is called when a marker is clicked with the locator

  If Left button is clicked on a marker, the marker is moved to
     a new position when the mouse button is released.

*-*-*-*-*-*-*-*-*-*-*Draw this marker with new coordinates*-*-*-*-*-*-*-*-*-*
*-*                  =====================================

void PaintMarkerNDC(Double_t, Double_t)
*-*-*-*-*-*-*-*Draw this marker with new coordinates in NDC*-*-*-*-*-*-*-*-*-*
*-*            ============================================

void Print(Option_t *) const
*-*-*-*-*-*-*-*-*-*-*Dump this marker with its attributes*-*-*-*-*-*-*-*-*-*
*-*                  ====================================

void SavePrimitive(ofstream &out, Option_t *)
 Save primitive as a C++ statement(s) on output stream out

void Streamer(TBuffer &R__b)
