If the wxGUI is not respecting the font selection made in
the Preferences gui, I would much rather we fixed the wxGUI than
add work-around options to all d.* modules.  d.barscale is in
the same boat.

moreover, while the rest of the GUI has matured nicely, I find
that overlay system for the decorations continues to be rather
awkward and we should consider to rethink the approach of how
they are added.

did we ever come to a solid set of instructions for folks who
want to use a different font for different rendering layers in
the wxGUI layer-list? Something like a 'Add grid or vector layers
overlay*' -> 'Add command layer' with a d.font call before the
layer which displays the text? does d.legend respect the selected
font if you add it that way via a custom 'Add command layer'
entry?

[*] the pull-down menu tooltip description seems not to match
contents of the menu very well. perhaps 'Additional layer options' or so?
