 label "Morrisville". The raster library supports writing such a range of
 values for all map types with Rast_set_cat(), but reading such a range of
 values is supported only for fp maps (FCELL, DCELL).

 integer maps as well?

 Yes, getting a label for a range of values now works for CELL maps as well
 (setting a label for a range of values was already possible).
