We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).
* Typo fixes.
* Navigation agent's `velocity_computed` signal is not emitted by
`set_velocity`, but at the end of that frame if `set_velocity` is
called.
* Simplify link in navigation agent's `avoidance_enabled` description.
* Unify `navigation_layers` description across `NavigationAgent{2,3}D`.
* Unify `is_normalized()` description across `Vector2`, `Vector3`, and
`Vector4`
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.
