Of course that released tar.bz2 file are not much smaller (though bz2 does not 
know how to remove obsolete information from png files..), but it also needs 
less space on _every_ koffice (or KDE installation).

For icons it's also a small runtime optimization: less data needs to be read 
from disk.

We have done that for KDE trunk before every major release (started IIRC at 
3.5). Nobody objected so far there... It has also been discussed in a b.k.o 
report.

I think SVN does just transfer diffs, even for binary files? Otherwise things 
would not have been committed with my slow connection within 5 minutes... So I 
think it's just about 6MBs for users to update. Please correct me if this 
assumption is wrong.

I have not thought that this is critical in any way. I have done that step by 
myself at least 3 times for whole KDE/ trunk and nobody objected.
