diff layer/TimeInstantLayer.cpp @ 17:0183ebb725ca

* Add ability to create empty layers for editing
* Add first basic editing capability (adding points to a time instant layer)
* Add various keyboard and mouse shortcuts for navigation &c
* Add ability to resize a selection by dragging its edges
* Add maximum zoom level
