fix pre-pause time leak

This is an important engine upgrade: idle events do not donate their timestamp to engine objects and pollute the timeline with unnecessary game ticks that can be represented as analytic continuations of previous game ticks.  This means that all "render" tick updates can be dropped from bot timelines.  In other words, progressing the physics simulation is invariant to differing subdivisions of an overall time advancement with no external input.
