Class Description

______________________________________________________________________________

  A TDrawPanelHist is a TDialogCanvas specialized to control
  histogram drawing options.
   With the mouse, the user can control:
     - the drawing range in X and Y
     - the drawing options
   When the DRAW button is executed, the selected histogram is drawn
   with the current parameters.

   Use the slider to control the range of the histogram to be drawn.

   The options are documented in TH1::Draw.

 DrawPanelHist default constructor.

 DrawPanelHist constructor.

 DrawPanelHist destructor.

 Add option to the current list of options.

 Collect all options and draw histogram.

 Create Draw, Defaults and Close buttons.

 Control mousse events when slider is used in a drawpanel

 This function is called by TPad::ExecuteEvent or TSliderBox::ExecuteEvent
 We return in the first case.
 When called by the slider,  px = 0 and py = 0

  when obj is deleted, clear fHistogram if fHistogram=obj

 Save this drawpanel in a macro.

 Set default draw panel options.

 Set graphics option "same".
