Finished fixing Wx IDs abuse. There was still some wasted IDs because of wx.NewId calls in many places where it wasn't needed, and those IDs were not re-used. As a consequence Beremiz was making exception crashing after a few hours of intensive use.
#!/bin/bash
INKSCAPE=inkscape
for i in `cat icons.svg |grep -o -e '%%[^%]*%%'|sed 's/%//g'`
do
if [ $i.png -nt icons.svg ]; then
echo "Skip $i"
else
rm -f $i.png
echo "$INKSCAPE" icons.svg -z -e $i.png -i $i
"$INKSCAPE" icons.svg -z -e $i.png -i $i
fi
done
