STOP_EVENT format

[Jerry]

For others who might have this question, the Viz3 way to find out if
an object has stopped moving (goto or spinto) is:

import viz

viz.go()

ground = viz.add('tut_ground.wrl')

ground.addAction(vizact.spinto(0,1,0,90,90))

def FinishedMoving(e):	

	if e.object == ground:
		print 'done'

viz.callback(viz.ACTION_END_EVENT,FinishedMoving)
