This function is probably useless for 99.9999% of our users.
You will need it only if you choose to write your own version STATE_engine_render()
The 3D_animation is updated automatically according to need each time that STATE_engine_render()
is called and the given object is seen. If one doesn't call STATE_engine_render()
(because one chooses to use his own renderer) then the 3D_animation frame is not updated.
Only in this case you should call this function so that your external renderer can benefit from
the 3D_animation API.
