Others better know the exacts, but resources are not reduced(1) with 
animation.

For more information, search the newsgroups for a keyword & feature 
added as an experimental feature to uberpov called #persistent. It 
allows parts of the SDL scene to be marked as persistent frame to frame.

(1) - With hard disk file caching, macro caching 'maybe' sometimes 
animation a tiny bit better. The animation mechanism occasionally gets 
used to create input to follow on frames and so due this carries a 
resource benefit.
