If there was no animation in the original mng, then
why
bother with the mng format? Why not change to png, update
the source code reference and be done?
Who knows?? I say we just use the .png. I suspect somebody
generated the .mng from the .png to begin with as a 'place-holder' for future
animation. The, for whatever reason, never followed through with the full
implementation. Either that, or the place-holder was just there for individual
distros to patch with their animated files. I know suse/opensuse had a couple of
different icons for the start menu that they would patch into kde3 back in the
10.x days.
Unless I read objections I will replace the MNG with a PNG and update the one source code
reference accordingly.
