Dick,
that was very helpful. Can you please tell me how to do this:

# I have not been a PNG maintainer, but want to be for 10 minutes:
$ ccmake .
Set MAINTAIN_PNGS to on, configure, generate, quit ccmake.

All in all it sounds easier for my to just send you the new .svg files
in a zipped folder. Would that be acceptable?

Thanks a lot for the explanation.

cheers
Fabrizio
