## About The Pull Request
Adds a couple helpers from #90354
1. `/proc/pick_recursive()` > able to take in nested lists and pick one
object from them. Works the same way `pick_weight_recursive()` does,
just without all the extra `_weight` stuff
2. `span_tinynicegreen()` > we had span_tiny for danger and notice but
not nicegreen, just filling that gap
3. `/matrix/proc/get_angle()` > Tells us the angle a matrix is currently
in
4. `GLOB.all_tool_behaviours` > in case you wanted an easy list for all
tool behaviors
5. `transition_filter_chain()` > a more complicated one, this is used if
you want to make an animation chain for a filter. (Thank you
LemonInTheDark for the help on this one.)
