EmitToolIndependentChange

(
    UObject* TargetObject,

A convenience function that is like EmitToolIndependentChange, but uses a FDynamicMeshChange that operates on the UnwrapCanonical of an input to create a change object that updates the other views and issues an OnUndoRedo broadcast on the input object.
