Alternatively, could I set the actor as 'manipulatable' - some how prevent
the stage from receiving input and send synthetic drag signals to the
actors? Seems to me that it would be easier and more logical to not set
actors as manipulatable and simply move them around using clutter functions
(I did try this by the way but it seems if I don't set an actor's mode, it's
not visible at all).
Looking forward to hearing back.
Thanks and great work.
