Thanks for this pointer, but is there a way to get it to dump a
Value2dDisplay? I can't seem to figure out how to do this (I tried
declaring a Value2dDisplay, then calling its setDisplayWidget method on
the BatchRaster object). I am trying to save gifs of a Discrete2d object.





  spaceDisplayWidget = [BatchRaster createBegin: self];
  spaceDisplayWidget = [spaceDisplayWidget createEnd];
  [spaceDisplayWidget setColormap: batchColormap];
  
  [spaceDisplayWidget setWidth: [webModelSwarm getXSize]
                Height: [webModelSwarm getYSize]];
  [spaceDisplayWidget pack];                     

  PrimaryDisplay = [Value2dDisplay createBegin: [self getZone]];
  [PrimaryDisplay setDisplayWidget: spaceDisplayWidget
colormap: batchColormap];
  [PrimaryDisplay setDiscrete2dToDisplay: [webModelSwarm 
getPrimaryField]];
  [PrimaryDisplay setDisplayMappingM: 256 C: 0]; 
  PrimaryDisplay = [PrimaryDisplay createEnd];


 // When updating I'm not sure what methods are appropriate -  
 // [PrimaryDisplay display]?  [spaceDisplayWidget drawSelf]?
