Added forcing time64 to be positive.  Fixes problem where large negative value overflows into int.
More careful computation of TimeToPosition() so floor is only called with in range values.
Re-instated 'true' flags for hiddenMid calls, which I'd mistakenly dropped, so that (later) FishEye can distinguish.
