Anim props fix batch 2

This patch series updates 4 filters to use new anim framework and does "this" -> "filter" or "frame" clean-up for additional 5 filters.

I'll do to 2 more pull requests in this series so that after these all "easy" filters in modules "core","oldfilm","kdenlive","plus" and "plusgpl" are converted to new anim framework and all filters are cleaned up to not use variable name "this" any more.
