Comment:

 I see your point, but this goes much deeper than just the d.barscale
 module, e.g. line width from d.vect exported with d.out.file and a large
 size= or resolution=4.

 GRASS 6's display architecture is inherently pixel based, and for visual-
 backwards compatibility reasons I would not like to change the default
 behaviour there. Perhaps as a new optional flag in 6.5svn, but really I
 think this is much better handled first in trunk, and with the additional
 capability of allowing SVG/EPS symbols with with d.mark addon module (see
 TODO on d.graph help page) + a new d.mark flag to indicate size= is
 percentage of frame sqrt(height^2+width+2), as is done with d.text font
 size.
