Leon Schittek 8a78c14d03 Nodes: Remove resize widgets from collapsed nodes 
Collapsed nodes had a specific widget to change their width.
Now that collapsed nodes are square rather than pill-shaped, the edges
can be used to resize them, just like in the uncollapsed state.
Therefore the scape widget can be removed.
