Fix gradual deterioration of cadence based rendering.
When a cadence based rendering sequence exceeds drift, we should not
count the over-rendered frame against the next in sequence. Doing
so causes an accumulation of errors.
Also extends the moving average for durations to 32 values and the
allowable drift to 16.66ms to stabilize the Catzilla 60fps and
Elite: Dangerous 60fps clips, which were hitting hysteresis very
frequently.
BUG=439548
TEST=new unittest.
