Geometry index won't be updated correctly if feature geometry is changed using `feature.setGeometry(new_geometry)`
ol.interaction.Snap should listen for a 'change:geometry' event on ol.Feature
More than one features can be be changed while handlingDownUpSequence
exampe: ol.interaction.Modify supports simultaneous editing of multiple features
When a geometry changes old indexed segments are searched by the feature extend and removed. New ones are added.
Old feature extent sholud be used when removing the old indexed segments.
handlePointerMove_ doesn't need to be called when dragging.
handleDragEvent_ takes care of the event in that case.
in handleDragEvent_, createOrUpdateVertexFeature_ doesn't need to be called for each dragged segment. it can be called only once with current vertex.
fixes made to pass the build
Prevent vertexFeature_ from ol.interaction.Modify from being selected by ol.interaction.Select.
The bug occurs when an delete attempt fails. ex: clicikng on the first or last node of LineString,
or clicking a line segment between two nodes.
This commit fixes the bug that occurs when trying to modify
a closed LineString by clicking on the starting/ending node.
Such a closed line is added to the modify-test example.
Fix a bug in ol.interaction.Modify when trying to delete nodes
on a geometry that has duplicate nodes. A bug occurs when
clicking on the duplicate node.
