Follow-up to #31925, `<member />` tags just before `</members>` would cause
a parsing issue, and we'd never notice that we're no longer parsing members.
Also added space before closing `/>`.
- Document a few more properties and methods
- Add more information to many classes
- Fix lots of typos and gramar mistakes
- Use [code] tags for parameters consistently
- Use [b] and [i] tags consistently
- Put "Warning:" and "Note:" on their own line to be more visible,
and make them always bold
- Tweak formatting in code examples to be more readable
- Use double quotes consistently
- Add more links to third-party technologies
The API docs for various animation nodes are pretty empty, yet the
tutorial at
https://docs.godotengine.org/en/latest/tutorials/animation/animation_tree.html
contains some details.
These details should be included in the API docs so looking up a
particular class actually provides some information rather than
requiring the user to hunt for a different tutorial.
This also links the AnimationTree tutorial and demo in the docs.
I've found the TPS demo to be the best resource so far for learning
how to use the AnimationTree. This should be easy to find if someone
looks up the AnimationTree API docs.
Finally, this fixes a param typo in AnimationNodeStateMachine.
