ol/interaction/ModifyFeature is an interaction for modifying feature geometries,
similar to the core
ol/interaction/Modify.
The interaction is more suitable to use to handle feature modification:
only features concerned by the modification are passed to the events
(instead of all feature with ol/interaction/Modify)
-
the modifystart event is fired before the feature is modified (no point still inserted)
-
the modifyend event is fired after the modification
-
it fires a modifying event in beetween.
