Flipping rendering order from (parent -> children) to (children -> parent)

Thanks for releasing such a great piece of software.

I'm wondering if there is a low-effort way to flip the rendering order of the tree from parent->children to children->parent, as shown in the diagram below. I've spent a few hours plugging away in the renderer to get a sense of things -- it's not clear whether a simple reordering of rows[] would work, or if it's substantially more involved. If someone more familiar with the renderer could chime in, that would be wonderful.


best wishes,
Peter
