Allow rotation transition around a fixed point without moving off-centered

[fraxinas]

I've got an issue here where I want to arrange a bunch of "slides" around a circular object and then continue "spinning" for every slide. unfortunately, this looks very funny because during the transitions, it rotates off-centered even though the control boxes were rotated around the exact center of the circle in inkscape ... please confer http://frax.ath.cx/rotate-test.svg i've also noticed that the "back" transition is off-centered even more than the "forward" transition maybe i'm just doing it wrong since i've just discovered sozi yesterday, but i find it really cool :)

During transitions, the camera moves along straight lines. The "back" transition includes a zooming effect.

A proposed feature is to allow attaching an arbitraty path to a transition. I don't know when it will be implemented.

just wanted to mention that i've added a link to my Blu-ray authoring presentation which i held at the Gstreamer Conference in Prague four weeks ago to the list on http://sozi.wikidot.com/presentations
