[GRASS-user] d.legend in python loop draws larger background than requestes

[Carlos Grohmann]

Ok, I run it again and it seems that the issue was with the size of the
background rectangle, the fontsize and the units string (' m') which all
ended up being larger than the predefined size.

Now I changed from using 'units' to 'title' and all the background
rectangles remain with the same size.

BUT....

For some mysterious reason, in some maps the legend has the lower value
(say, zero) at the bottom and the upper value (1700) at the top, and in
other maps, it is inverted! Zero is on top and 1700 on the bottom...
