Variable documentation

This is 2 points instead of start/end because the 2nd point can be dragged past the 1st point so the order gets swapped.

Should be compared each time to see which one is first.

nframes_t Transport::position

Transport position in frames.

FIXME is this used?

ZixSem Transport::paused

This is set when record is toggled and is used to check if a new region should be created.

It should be set to off after the first cycle it is processed in in the audio engine post process. Paused signal from process thread.
