 I noticed couple of problems with legend for CELL rasters when we use flag
 -s (smooth gradient):

 1. How to test:  `d.legend -s raster=basin_50K at PERMANENT`. Instead of the
 colors, I can see only black. This is result of the recent changes, still
 works in 7.2.

 2.`label_values` and `label_step` don't work with the command above.
 `label_values=2` report: `tick_value=2 out of range [0.000, 0.000]` and
 `label_step` doesn't do anything.


 3. `d.legend -s -d raster=basin_50K at PERMANENT` shows histogram, but it
 looks vertically shifted. This is an old bug present in 7.2.
