[FFmpeg-devel] [PATCH v2] doc/filters.texi: complete rewrite of fps filter doc, v2.

[list+ffmpeg-dev at jdlh.com]

Thank you for the review. Here is a rewrite of the improvement to the fps filter
documentation, based on those comments.  Thought it was too wordy before? It now 
has 11% fewer words.                             

To confirm, no other documentation and no code are affected by this patch.

Comments?
