Description
It can be confusing in Pitivi if a small clip disappears behind a larger clip. It can also be confusing why a transition is not created, since the two clips overlap.
Option 1: Disallow it like it is disallowed to have more than two clips overlapping at any single point, hopefully making things simpler without any loss in functionality.
Option 2: Always show clip2 on top of clip1. Clients will have to take care to display the widget for clip2 on top of the widget for clip1, currently in Pitivi it's possible for clip2 be completely under clip1 which is the larger one.
Option 3: Depending on [[ http://lazka.github.io/pgi-docs/#GES-1.0/classes/Layer.html#GES.Layer.props.auto_transition | GES.Layer.props.auto_transition ]]:
- if auto_transition is True, create a transition which goes 0% -> 100% -> 0%, to avoid
- if auto_transition is False, same as Option 2.
