      Color swatches for categorical scalar bar. · e7f4e894
      David Thompson authored
      When a `vtkLookupTable` with `IndexedLookup` set to true
      is passed to `vtkScalarBarActor`, the scalar bar is not drawn.
      Instead, a set of distinct color swatches is rendered -- one
      for each annotated value stored in the lookup table.
      The labels stored with each annotation are not yet rendered.

      Make annotation API more consistent. · dd7fe488
      David Thompson authored
      + Make `GetIndex()` work consistently whether `IndexedLookup`
        is true or false.
      + Make `GetIndex()` and `MapValue()` properly handle NaN values
        when `IndexedLookup` is false.
      + Return a `vtkIdType` for the number of annotated values.
        (The previous `vtkVariant` was a cut-and-paste error.)

      Before we add user-specified annotation, make it clear
      that the pre-existing text annotations were all tick marks.

      Color mapping using only annotated values. · ee78433e
      David Thompson authored
      This patch implements an "indexed" color mode for `vtkLookupTable`.
      When `IndexedLookup` is true, the scalar range and log/linear settings are disabled;
      `MapScalars` and `MapValue` require an exact match to an annotated value
      in order to return a valid color.
      All other values are mapped to `NanColor`.
