Looping over each object and baking its action is going to cause a feedback loop in some cases - if one object is constrained to another for example.

This functionality should be changed so the animation plays through once, baking all data at once to avoid result depending on object order.

It's also more efficient to bake in one pass.

Thinking of how this can work without having to complicate the API by passing a list of objects & actions.

This could be done by making the bake function into a generator, psudo-code::

bake_state = []
for obj selected:
    some_action = ...
    bake_state.append(bake_action_generator(obj, ... action=some_action))

for frame in range(frame_start, frame_end + 1):
    for s in bake_state:

# send None as a signal to finish
for s in bake_state:

This way the bake functions can be controlled by a main time loop,
for working example code that uses a similar convention, see:
