The only use of C4RTF in its final moments was parsing out plain text
from RTF files anyway, so why even go to all the trouble instead of just
storing plain text in the beginning?
libpng >1.6 keeps nagging because of that.
Quick bash script to do so:
find . -name *.png \
| while read f; do
n=$(pngcrush -ow -rem allb-reduce "$f" 2>&1 | grep -c 'incorrect sRGB');
if [[ $n -gt 0 ]]; then
git add "$f"
else
git checkout "$f"
fi
done
