SH-3931 WIP Interesting: Add graphs to visualize scene load metrics

added getAs and setAs to LLUnit to make it clearer how you specify units
removed accidental 0-based indexing of periodicRecording history...
should now be consistently 1-based, with 0 accessing current active recording
removed per frame timer updates of all historical timer bars in fast timer display
added missing assignment operator to recordings
