        Looks lovely, as/when there are dev-builds we should poke the artists
about it so they know it's there & get them excited about it :-)

        So - one minor problem here is that, we do this system-call thrash for
each icon for a file that is not there :-) I'd rather prefer that we
require the images/ directory to exist at startup - if it is there, we
always do the lookups first in there and turn the cache off - otherwise,
we never look in there.

        Any chance of a minor follow-on tweak to do that ? the strace of a
normal startup without that directory should not have scads of opens
of .pngs.

        Thanks for that, can you close the easy-hack bug too ? :-)

        Nice work,

                Michael.
