scripts: Changed most tree renderers to be pseudo-standalone

I'm trying to avoid having classes with different implementations across
scripts, as it makes updating things error-prone, but at same time
copying all the tree renderers to all dbg scripts would be a bit much.

Monkey-patching the TreeArt class in relevant scripts seems like a
reasonable compromise.
