The version converted with imagemagick looks pretty horrible, particularly
for Team Arena (I suspect it's getting layer modes wrong), so I'd really
prefer not to rely on that. I think we have to either continue to use
xcftools, or include pregenerated PNG versions in the source package
and re-export them with gimp if they ever get modified.
