//  Class:  avtPseudocolorPlot
//
//  Purpose:
//      A concrete type of avtPlot, this is the standard pseudocolor plot.
//
//  Programmer: Hank Childs
//  Creation:   December 28, 2000
//
//  Modifications:
//
//    Jeremy Meredith, Fri Mar  2 13:10:02 PST 2001
//    Made SetAtts virtual and take a generic AttributeGroup.
//
//    Jeremy Meredith, Sun Mar  4 16:59:57 PST 2001
//    Added a static Create method.
//
//    Hank Childs, Tue Mar 27 14:47:03 PST 2001
//    Inherited from avtSurfaceDataPlot instead of avtPlot and added GetName.
//
//    Kathleen Bonnell, Tue Apr  3 08:56:47 PDT 2001 
//    Made PseudocolorAttributes a data member so other methods can have access
//    to the atts.  Added SetScaling, DefineLogLUT, and DefineSkewLUT methods. 
//
//    Kathleen Bonnell, Tue Apr 24 12:22:01 PDT 2001
//    Added avtShiftCenterFilter. 
//    
//    Jeremy Meredith, Tue Jun  5 20:45:02 PDT 2001
//    Allow storage of attributes as a class member.
//
//    Brad Whitlock, Thu Jun 14 16:49:22 PST 2001
//    Added SetColorTable method.
//
//    Kathleen Bonnell, Wed Aug 29 16:44:31 PDT 2001 
//    Added avtLookupTable and previousMode. 
//
//    Kathleen Bonnell, Thu Oct  4 16:28:16 PDT 2001 
//    Added SetLimitsMode.  Removed SetMin, SetMax, SetMinOff, SetMaxOff.
//
//    Kathleen Bonnell, Wed Mar 13 12:04:53 PST 2002 
//    Added private method SetLegendRanges.  
//
//    Kathleen Bonnell, Thu Mar 28 14:03:19 PST 2002 
//    Removed previousMode, no longer needed. 
//
//    Hank Childs, Sun Jun 23 12:19:23 PDT 2002
//    Add support for point meshes.
//
//    Kathleen Bonnell, Tue Oct 22 08:33:26 PDT 2002
//    Added ApplyRenderingTransformation. 
//    
//    Jeremy Meredith, Tue Dec 10 09:06:18 PST 2002
//    Added GetSmoothingLevel to allow smoothing inside avtPlot.
//
//    Eric Brugger, Thu Mar 25 16:59:55 PST 2004
//    I added the GetDataExtents method.
//
//    Kathleen Bonnell, Thu Aug 19 15:29:46 PDT 2004
//    Added EnhanceSpecification, and topoDim ivar.  Replaced glyphPoints
//    and varMapper with glyphMapper.
//
//    Kathleen Bonnell, Tue Aug 24 15:31:56 PDT 2004 
//    Added SetCellCountMultiplierForSRThreshold.
//
//    Kathleen Bonnell, Tue Nov  2 11:01:28 PST 2004 
//    Added avtPseudocolorFilter.
//
//    Kathleen Bonnell, Fri Nov 12 11:25:23 PST 2004
//    Replaced avtPointGlyphMapper with avtVariablePointGlyphMapper. 
//
//    Brad Whitlock, Thu Jul 21 15:25:44 PST 2005
//    Added SetPointGlyphSize.
//
//    Hank Childs, Wed Aug 13 13:46:31 PDT 2008
//    Add NeedZBufferToCompositeEvenIn2D because thick lines can bleed into
//    other processor's portion of image space.
//
//    Jeremy Meredith, Fri Feb 20 15:09:22 EST 2009
//    Added support for using per-color alpha values from a color table
//    (instead of just a single global opacity for the whole plot).
//
//    Kathleen Biagas, Tue Aug 23 11:25:34 PDT 2016
//    Add VariableMapper as points and surfaces no longer handled by the
//    same mapper.
//
//    Kathleen Biagas, Wed Aug 24 15:42:56 PDT 2016
//    Change use of avtVariableMapper to avtPseudcolorMapper, a specialization
//    of avtVariableMapper that utilizes a special vtk mapper.
