Graphs are usually large, needing a lot of horizontal scrolling and
they can include more information for debugging.

This patch makes graph more compact horizontally by splitting
labels in lines and removing namespaces.
Furthermore it adds following information:

• Operation ID.
• SetValueOperation float value.
• Optionally, operation node name.

Operation ID allows to differentiate between instances and when there are no tree changes they should be the same on next debugging execution.
Operation node name is optional because most of the time it can be deduced and clutters graph with text. But there are cases
like TranslateOperation issues that is useful to know if it comes from a node and which.
