Iam not sure what could be discussed on this ?
making the values parametric using libavutil/eval maybe but this could
be a seperate patch afterwards too
Also one could support using some mask image that "lists" what should
be used and what not but thats not the same as a simply specifyable
rectangle.
thus once you removed all the tabs i think the patch is close to
being ok.

Further improvments are of course possible and welcome!
