Replace the 60Hz granularity with which TimerInterrupt() is normally called
(by INTFLAG_VIA) with a proper, high-resolution timer interrupt
(INTFLAG_TIMER).

Enqueue time tasks with different durations and compare the actual elapsed
times obtained from Microseconds(). Without PRECISE_TIMING you should see
the 60Hz quantization. With PRECISE_TIMING it should be better.
