Animations and OSGB

[fabioped]

What I expected from vizard was the ability to:
- play the animation from start, whatever the current state is
- stop the animation to frame 0, whatever the current state is

Even doing this:

def update(e):
print model.getAnimationFrame(), model.getAnimationTime()
viz.callback(viz.UPDATE_EVENT, update)

get's me nothing more than 0's during the animation
