Nice! :-)  Thank you a lot!

To check that everything is still the same, I created a script that
checks 2 directories (original icons, and the optimized ones), converts
the png's to xpm's and checks them for differences:

http://cgit.freedesktop.org/libreoffice/build/tree/bin/check-artwork.sh

Unfortunately, some of the icons differed - please see the attached
list; I did not commit/push those, only the ones that were the same.

Can you please check what was wrong?  I eg. see that
svx/res/lightfromleft_22.png has originally a transparent background,
but the optimized version has gray background.

Done :-) - with the exception of the attached list.

Thank you a lot,
Kendy
