This is not a bug, it's a feature and an inconsistency among the greater
scheme of GRASS modules.

Sure something can be done about it (for 6.0+).


It is fully documented:

d.barscale --help
   at   The screen coordinates for top-left corner of label
        ([0,0] is top-left of frame)


d.text --help
   at   Screen postion at which text will begin to be drawn
        (percentage, [0,0] is lower left)


also affects d.text.freetype, d.legend, d.frame ....



d.text.freetype is interesting:
  -p   Coordinates are in pixels ([0,0] is top left)
  -n   Coordinates are percentage of frame ([0,0] is bottom left)

& generally the way around I would think logical - pixels use i,j
convention; more abstract "percent of window" uses x,y convention.
