Detailed Description

A time:Position object decoded into LV2's own units and conventions.

Each field carries its own presence flag because a host sends only the properties it knows: time:frame + time:speed from a plain sample transport, the full musical set from a tempo-aware one. The flags become TransportValidity bits on ProcessContext, so a processor can tell an unavailable value from a default one.
