Need better way to lookup shapes from models

[bergel]

in particular to cope with composite shapes

I think this issue is related to this pull request from Massimo https://github.com/ObjectProfile/Roassal3/pull/273

Is this issue still valid?

[bergel]

Consider the following code:

canvas := RSCanvas new.

outerShapes := RSComposite models: #(10 20) forEach: [ :s :nb |
	s add: (RSCircle new color: Color blue; model: (nb + 1)).
	s @ RSPopup.
	s
	 ].
outerShapes do: [ :ss | ss padding: 3 ].
outerShapes @ RSPopup @ RSDraggable.
outerShapes color: Color veryLightGray.
canvas addAll: outerShapes.
RSFlowLayout on: outerShapes.

lb := RSLineBuilder line.
lb withBorderAttachPoint.
lb canvas: canvas.
lb shapes: (canvas deepShapesFromModels: #(11 21)).
lb connectTo: [ :nb | nb + 10 ].

canvas zoomToFit.

The line builder should have a configuration flag, maybe deepSearch, to look for the inner nodes.

We could have a RSTDeepSearch that is used by RSTContainer and RSGroup. But there is privateNodes and privateEdges that must only use children / shapes. Currently it is messed up

[bergel]

Very similar to issue #279

[akevalion]

users should use deepShapeFromModel:
