    Maps discrete integer class values (land-use / soil / zone codes)
    to colours, the raster analogue of CategorizedRenderer on the
    feature side. Each class carries a value, a human label, and a
    colour. Classes not explicitly listed fall back to a wrapping
    CategoricalPalette lookup so an unclassified raster still draws.

    Implements IRasterRenderer so GISRasterLayer can swap it in via
    setRasterRenderer().
