Size, Position & Rotate Video Filter

A couple of comments about documentation:

  • once you add content to a topic, remove the “If you are a trusted user you can edit…” Eventually, these topics will be compiled into PDF ala book (minus the comments).
  • I do not want every filter topic to contain information about how to use filters in general, which is basically all we have here. That is a separate topic. This topic is about the Size and Position filter only.
