[Paraview] Getting the actual keyframe index

[Utkarsh Ayachit]

Not as easy as it sounds since ParaView doesn't really have a notion
of key-frame index. But try adding a new "Python" animation track and
then using a script something like follows. When you play the
animation you'll see the index increasing.

#----------------------------------------
def start_cue(self):
    global index
    index = 0
    print "start", index

def tick(self):
    global index
    print "cur", index
    index = index + 1

def end_cue(self): pass
#----------------------------------------
