It would be nice if one could add the name of the unit used in the scalebar,
e.g. meter, kilometer. Furthermore an option where one can choose in what unit
the numbers of the scalebar should be displayed, i.e. meter or kilometer, etc.
would be nice.

Reasons

to 1st request: generally it seems more appropriate to have the unit displayed.
to 2nd request: Having a map of the scale 3.000.000 or something like that a
scale bar with units in meters (e.g. in UTM) seems also not very nice - its OK,
but a scalebar with kilometer  units would be nicer in this case.

NVIZ scalebar in 6.3-cvs has somthing like this already. Due to 'length' and
'segments' commands in 'scalebar' we have to be careful that the result does
not get messy.


For now you can manually place units label with the "text" instruction.
It's a pain, but it works.

scalebar
  where 2.95 15.15
  length 10000
  segment 5
  numbers 5
  background n
  end
text 21.5% 2.6% Meters
  ref bottom center
  end
