I was considering to make orp.pl understand a --scale option.  Then
tilesGen.pl would be in control of it as well as the Inkscape
parameters.  Didn't know there is a "scale" parameter in the style
sheets...

Correct me if I am talking stupid stuff.  Inkscape knows a
--export-area-canvas option.  Could or/p set the canvas size?  Then
the client wouldn't need to know.
