I'd rather not tie this to HUD layer so strongly, and instead make it
"LayerTreeDebugSettings" or something. And include the layer borders debug
option in it. That way we can potentially toggle layer borders in the future
through inspector, and doesn't tie the design to the HUD layer for future debug
visualizations.
