GraphFrame is a special [GraphElement] to which other [GraphElement]s can be attached. It can be configured to automatically resize to enclose all attached [GraphElement]s. If the frame is moved, all the attached [GraphElement]s inside it will be moved as well.

A GraphFrame is always kept behind the connection layer and other [GraphElement]s inside a [GraphEdit].
