there is AthensSceneView
(read its class comment, its really easy to use)
for transition , i implemented a special morph, AthensWrapMorph
which wraps (as its name says) its children morphs and forces them to be
rendered by athens
(the child morphs will never receive #drawOn: but #drawOnAthensCanvas:
Like that you can start using athens for current state of morphic and
later, when whole World will be rendered
by athens, you will no longer will need to use wrapper, so you will just
throw it out from hierarchy without changing your existing code.
