TransitionGroup is meant to be used to group transitions on different
properties, so you can give them the same duration, delay, and easing
mode.

yes, transitions are automatically started when you add them to an
actor with add_transition(). you can use the ClutterTimeline API
(since a Transition is-a Timeline) to control the state of a
Transition, though.

you can also create Transition instances and keep them around, and
only add them to an actor when needed, and remove the transition when
it's complete.

ciao,
