Well, my idea was to use the optimizer as part of the installation process, so 
the "source" SVG files would still contain the complete editable version.

Or the optimizer could be used just before preparing the package to keep size 
down.

Se above. But at the moment I'm not touching the coordinate precision...

Does it really make a difference? Higher compression affects compression time,
normally decompression time does not increase much.

Mauricio main objection was that a contributor would have access to a worse 
copy of the data files as a starting point. Which is a valid concern.

However, I think a better way to attract/help contributors is to point them to 
a wiki page (or something similar) with instructions and a few templates -- 
or the "source" files for the shipped themes. At the moment I think it's 
quite difficult for the casual user to find out where the data files are 
stored, and the conventions that need to be respected -- the source files are 
at least organized per application.  

The problem is -- that's more work. But we'll really have that problem when 
hotnewstuff gets implemented in the games.

At least, I hope we get some problem at that point, because otherwise that 
would mean that our wicked plan to lure new artists through kdegames has 
failed. :)
