Description copied from interface: EditorProvider

Returns an editor for processing changes between the given two states. Returns null if the changes don't require processing.

An implementation of this method should generally not compare the given before and after states, as the caller is expected to compare the states and invoke the respective callback methods on the Editor instance returned by this method. Instead the implementation can use the opportunity for other preparatory work.
