Anyone interested in GIF animation output from Chimera? Their main
appeal is that they play directly in most web browsers (like banner ads).
It was easy to add to the Chimera movie recorder using ffmpeg which is
included in the Chimera distribution. But ffmpeg uses a fixed color
palette causing severe color banding and does not offer LZW compression
resulting in large file sizes. That option looks unusable. I tried
another approach using a separate program called "gifsicle". That gave
decent coloring and compression but it would require adding gifsicle to
the Chimera distribution. I am reluctant to do that (entails future
maintenance) unless there is strong interest in making GIF animations.
