diff layer/TimeInstantLayer.cpp @ 387:f329416bf1a5

* Permit holding Shift while dragging an instant or other edited thing,
  to override the initial drag resistance (for #1928943 sticky time
  instants)
* better handling of updates during progressive decode load
* ready() signal from model (used by vect)
