 I thought about a possibility to reset a feature of an
 OpenLayers.Control.TransformFeature, like when activating this control the
 first time (feature is null and naturally no box is drawn).

 When trying to call setFeature(null) on this control (e.g. to signal the
 control to loose any information about the just transformed feature) an
 error (in setFeature method) says "this.feature" is null.
 Therefore a way how to force the behaviour of the control on each
 activation to have the necessity of a feature to be set by a user first
 would be great, e.g. some workflow doing an unsetFeature(..) action, which
 might be applicable by this provided patch (please review!).

 Thanks
