And now for something much more exciting: the first work for upstreaming bevy_mod_picking! We're doing this in chunks: copy-pasting portions of the library with minimal adaptation to start. Once that's all in place, we'll make sure it works, add examples and do some tech debt cleanup.
I'm feeling good about getting this in place for 0.15 :D Sorely needed, and it'll be nice to share the load in its maintenance.
