True if interactive geometry edits made using the GeometryEditor should happen using the current SnapSettings, false otherwise. Default is false. If SnapSettings.isEnabled is true and a user edits a geometry interactively, then when the pointer is close to an existing snappable feature, the position of the interactive edit is adjusted to coincide with ("snap to") that feature. The content of SnapSettings.sourceSettings determines which sources of geometries can be used to snap to.
