Issue 834 in moose-technology: Roassal layouts do not properly take into account userDefinedEdges

Take into account the following visualization:
http://www.themoosebook.org/book/internals/famix/meta-browser

The layout is only affected by the gray edges. Although the red edges
reside in the same graph, they do not affect the position of the nodes
(like this you obtain the tree as a base map and the red edges as
extra details for a selected node). This is achieved by telling the
layout to only consider the gray edges as "userDefinedEdges".

Cheers,
Doru

Can you describe how userDefineEdges fit into the system ?

New issue 834 by [hidden email] Roassal layouts do not properly
take into account userDefinedEdges
http://code.google.com/p/moose-technology/issues/detail?id=834

To reproduce see the example below:
| edges |
view nodes: #(1 2 3).
edges := view edgesFrom: [:each  | each - 1].
view shape line color: Color red.
view edges: #(3) from: [:each | each - 2] to: #yourself.
view treeLayout userDefinedEdges: edges

If the user defined edges would be taken into account, the tree would
appear on one line (1->2->3). Instead it appears laid out as 1->2, 1->3 .
