Minimum Rendered Size for a Node

[settergren]

Is there a way to apply a minimum rendered size for a node, such that when zooming out, the rendered node will stop getting smaller at a certain size?

I have a custom layout that potentially causes nodes to be separated very far apart and I need to zoom out a lot in order to see the full picture. However, this causes the nodes to be sized with a zero width/height. I'd like to set the minimum rendered width/height to 5px (or something like this) so that way I can always see and interact with the nodes.
