polymer: fix animations that loop to frame 0

Browse source 
With VBOs enabled, the virtual pointer to the geometry of frame 0 of a model
is always NULL. This was confusing the polymer code responsible for deciding
whether to enable smooth animations or not, which meant that any animation
that would loop to frame 0 would do it as if animation interpolation was
disabled, which looks very choppy.
