[Chimera-users] Save as GIF (animated or otherwise)

For ease of editing. I don't know an easy way to edit MP4 files frame by
frame and add labels etc, whereas it is straightforward for GIF files, and
for many animations (e.g. a simple density map or model morph) I don't need
more than 256 colors. If animated jpegs or png exist I would be happy with
that too, but I wasn't aware of such.

Cheers,
Oli
