I noticed that png files are not optimized - size can be losslessly reduced
using optipng [1] and then advdef [2] with:

find . -name "*.png" -exec optipng -o5 '{}' \;
find . -name "*.png" -exec advdef -z -4 '{}' \;

I also noticed there are some gif images that can be converted to png to
save size in:
./services/editor/htmlarea/images/
./services/editor/htmlarea/plugins/TableOperations/img/
./themes/
and possibly other directories.
