Unable to set 'speedup' running headless (ie. --gui)

[jacobperron]

We can set the desired real-time factor (aka. speedup) by placing the following in our world file:

    # Set 10x real-time
    speedup 10 

But this seems to only work when running with the GUI enabled. As soon as I run headless (e.g. stage --gui my.world), the simulation seems to run as fast as possible (as if speedup 0 was set).

It would be nice to be able to set the speedup factor regardless of whether the GUI is enabled. This would allow running headless simulations with distributed systems (e.g. ROS) with processes that may not be able to keep up with how fast the simulation is progressing.

That’s an interesting use case I’ve never considered. Will think about it.
