Change b279020f added properties (o.vx and o.vy) to explicitly provide
vertex coords. As implemented, if no verticies were provided they
were computed (as before). However, they were only computed on the
very first frame which broke the existing behaviour where by
the vertex coords were computed on each frame and so could be
dynamic.

This change restores that behaviour.
