Lookup Table Editing

One of the ParaView 2.4 functionality we have to duplicate and potentially improve on the Qt interface is the lookup table editing. Currently, ParaView 2.4 has a special way of handling lookup tables. There is one lookup table per array name. When a display is first colored by an array, ParaView checks if a lookup table for that array exists. Something like:

  vtkPVColorMap* colorMap = this->GetPVWindow()->GetPVColorMap(
    arrayname, arrayInfo->GetNumberOfComponents());
  this->ColorByArray(colorMap, field);
