When the SVG version of an icon has been updated, it is possible to get
automatically the PNG updated by running the following:

  for file in *scalable*.svg; do
    for size in 16 22 24 32; do
      inkscape -w $size -e `echo $file | sed -e s/scalable/${size}x${size}/ -e s/svg/png/` $file
    done
  done
