When creating a new map based on an existing using r.mapcalc, the color table of the old map is used for the new map. However, if the new map only contains a subset of the values of the old map, how can I trim the color table so it only contains color definitions for the values present in the new map? Any easy (automatic) way to do this? Note, this is probably only useful for integer (category) maps.
