Yes, that was my fault, I labeled them backwards.

Right, Josh kept them in the source directory but they aren't installed
anymore. There is nowhere in the Zenmap interface where the icons are
shown at anything other than their PNG sizes. The Windows build has
always used PNGs as far as I know and nobody knew the difference. If we
introduce some scalable view then we can think about putting them back.
