I verified this experimentally. I added a point at roughly (1,0,0), and
dragged a handle back to the origin. The result was:
```
get_point_position: (0.991079, 0, -0.000069)
get_point_in: (0.993409, 0, 0)
get_point_out: (-0.993409, 0, 0)
```
(cherry picked from commit c6093ae612)
We already removed it from the online docs with #35132.
Currently it can only be "Built-In Types" (Variant types) or "Core"
(everything else), which is of limited use.
We might also want to consider dropping it from `ClassDB` altogether
in Godot 4.0.
- 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
Rename user facing methods and variables as well as the corresponding
