THX for the detailed explanation
btw:
- the replay functionality needs a box where the user can adjust/enter a start-time and the replay just 'starts' from there.
(from the nature how the replay is generated as rerunning the simulation, it would calc the replay in the background but not draw the
display at all, just show a "
Winding Forward"-message until the starttime is reached .... i 'guesstimate' that will highly speed up
the simulation-calcs and the waiting-time will be not to long)
