It was added, along with Recode and Categorize, in preparation for
supporting the Symbology Encoding 1.1 spec for raster styling. Here is
an example taken from the spec:

<RasterSymbolizer>
  <!- various styling stuff, then... -->
  <ColorMap>
    <Interpolate>
      <LookupValue>Rasterdata</LookupValue>
      <InterpolationPoint>
        <Data>0</Data>
        <Value>#000000</Value>
      </InterpolationPoint>
      <InterpolationPoint>
        <Data>255</Data>
        <Value>#ffffff</Value>
      </InterpolationPoint>
    </Interpolate>
  </ColorMap>
</RasterSymbolizer>
