Play Panel counter reflecting actual time point of score

1. Open score (credit to Bill Watkins).
2. Open Play Panel.
3. Increase BPM to the full.
4. Play.

Currently, the counter is real time (like watching a normal clock). I think there should be an additional counter that represents the actual time point of the score (as if you were playing normally at 100% BPM), despite playing at another BPM.
