#3265: min and max value options for r.colors
 Reporter:  veroandreo   |      Owner:  grass-dev@…
     Type:  enhancement  |     Status:  new
 Priority:  normal       |  Milestone:  7.2.1
Component:  Raster       |    Version:  unspecified
 Keywords:  r.colors     |        CPU:  Unspecified
 Platform:  Unspecified  |
 In the present state, in order to make color scales equivalent among maps,
 as there are not min and max value options in r.colors, one should feed
 r.colors with the list of maps, so it takes min and max from there.

 This leads to repetition because one cannot set r.colors iteratively for
 each map immediately after they are created, but it has to be done once
 all of them are created, and then iterate again to create displays (png
 outputs), for example.

 With min and max value options (for those cases in which one knows before
 hand the range of valid values in maps) this could be attained in a single
 loop immediately after creating each map, with no need to loop all over
