As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
The main change is to caculate tangent directly from bezier curve, without going
through discretized polyline, avoiding pitfalls of discretization.
Other changes are:
1. Add an bezier_derivative() method for Vector3, Vector2, and Math;
2. Add an tesselate_even_length() method to Curve3D, which tesselate bezier curve to even length segments adaptively;
3. Cache the tangent vectors in baked_tangent_vector_cache;
This is not enabled by default in the core version for performance reasons,
as Vector/CowData are used in critical code paths where not zero'ing memory
which is going to be set later on can be important.
But for bindings / the scripting API, we make zero the new items by default
(which already happened for built types like Vector3, etc., but not for
trivial types like int, float).
Fixes#43033.

On #43310, class reference was automatically updated from source,
causing xml documentation to disagree with parameter naming
description on Plane.intersects_segment().
Weirdly, it also changed the parameter for Plane.is_point_over()
from point to plane, when only the first has sense (and it is
defined on math.Plane as "const Vector3 &p_point"). Manual
mistake?
* Update begin/end to from/to on Plane.intersects_segment(...)
docs description to match source
* Update Plane bindings to use points instread of plane for
is_point_over(...)
* Change Plane.is_point_over(plane) to Plane.is_point_over(point)
AND its description on docs
Fixesgodotengine/godot-docs#5976
Implement built-in classes Vector4, Vector4i and Projection.
* Two versions of Vector4 (float and integer).
* A Projection class, which is a 4x4 matrix specialized in projection types.
These types have been requested for a long time, but given they were very corner case they were not added before.
Because in Godot 4, reimplementing parts of the rendering engine is now possible, access to these types (heavily used by the rendering code) becomes a necessity.
**Q**: Why Projection and not Matrix4?
**A**: Godot does not use Matrix2, Matrix3, Matrix4x3, etc. naming convention because, within the engine, these types always have a *purpose*. As such, Godot names them: Transform2D, Transform3D or Basis. In this case, this 4x4 matrix is _always_ used as a _Projection_, hence the naming.
