Support use of rsvg-convert to create pre-scaled icons

[Gerritv]

On many development platforms (Ubuntu, Scratchbox, etc) ksvg2png does not exist. To add it requires installing KDE which is generally a 130mb exercise. A simpler solution is to use rsvg-convert, which installs from librsvg2. Patching navit/xpm/navit_svg2png with the below switches it to use rsvg-convert.

Ticket has been solved in rev 2002, in a slightly different way : navit-svg2png will now use either ksvntopng, rsvg-convert, or inkscape according to which one is available. Thanks for your patch!

Hi.

I'd like to request a priority change of the svg-conversion tools used.

As described here ​https://bugs.kde.org/show_bug.cgi?id=186566 , I hit a bug crashing my computer using ksvgtopng. Also, I would suggest preferring ksvgtopng4 over ksvgtopng.

This is the patch I propose:

oh, convert is part of the imagemagick toolkit, which is installed on lots of linux machines; de-facto standard on gentoo at least.

i was able to build successfully with this patch.

You can use now:

  --with-svg2png-use-convert   use imagemagick's convert for png creation
  --with-svg2png-use-rsvg-convert   use librsvg's rsvg-convert for png creation
  --with-svg2png-use-inkscape   use inkscapes internal convert routines for png creation
  --with-svg2png-use-ksvgtopng4   use kde4's ksvgtopng4 for png creation
  --with-svg2png-use-ksvgtopng   use kde3's convert for png creation
