See the commit message of the attached patch to understand what it does.

The idea is that with absolute radius the user has to always know the video
size to get a predictable result while this way the user who knows the video
size can calculate the relative radius and set it and the one who doesn't can
just set a the relative one and be happy.
Also makes "radius" more consistent with "x-center" and "y-center" properties.

Currently the radius is defined with respect to the circumscribed circle
because it seemed more intuitive to me. The inscribed circle would probably be
good too, I guess it's a matter of personal preferences, Tell me what you like
more.
