Possibly each respective xcf file too, but I'm thinking
we delete the xcf files.
That would get rid of the high resolution editable/layered source file. Don't do that! :-)
Perhaps then we need a wiki article how to maintain the xcf files, why we do that, and how to convert to png using our own apps. We should eat our own dog food. I dislike the idea that we need to use gtk apps to maintain our foundations. Just does not set right or feel right. :-)
