- playback timer uses the audio output device as its master clock: the
PortAudio callback counts consumed frames (including underrun
zero-fill) so video cannot drift away from what is heard; wall clock
remains as fallback when no clocked output is running
- output clock compensates for device output latency; new Preferences >
Audio buffer size setting (0 = auto)
- SampleBuffer::speed() now uses linear interpolation instead of
nearest-neighbor sampling
- regression tests: audio-clock driven timer (fwd/rev/speed), wall
clock fallback, interpolation correctness
