* When configured with a `source` or `features`, the modification object (for
* point geometries the point, for linestring or polygon geometries an existing
* vertex or a new vertex along a segment) is determined by geometric proximity to
* the pointer location. When configured with a `layer`, hit detection will be

* When configured with a `source` or `features`, Cartesian distance from the
* pointer is used to determine all features that will be modified. This is the
* preferred mode for modifying polygons or linestrings with shared edges or
* vertices that have to be modified together to maintain topology.
