If the programmer creates a view object, s/he creates a specialised window with an editor displayed inside it. The view delegates to its editor object and the programmer does not have to be aware that the view consists of multiple objects. Class editor however sometimes invokes associated messages (for example editor<->error_message. We would like to retain the invisibility of the multiple objects by binding @receiver to the view rather than to the editor itself.

The visual<-master method is a (bad, but we needed something) attempt to solve this problem. It knows about some of these combinations and will return the proper main object.

Defaults: Visual objects that have not redefined this method return object<-self

Bugs: This method should not be there. As soon as a better solution to this composite object problem is found we will replace this.
