 3D rasters can either be 'float's or 'double's. But r.to.rast3 always
 creates doubles. For a 3D raster with many many cells this can be a rather
 expensive problem.


 ps- why no raster 3d support for integers? (e.g. category == geologic rock

 pps- why not FCELL,DCELL to match 2D rasters? or are they anachronisms
 from an era when IEEE FPs were still in strong competition with IBM's FP,
