c920a4f051 [Fixed] for "off-by-1" bug when sampling "baked" curve data towards the end of the curve.
[Fixed] Failing test "[Curve] Custom curve with free tangents" by setting the curve's `bake_resolution` to 11.
[Fixed] test messages in "[Curve] Custom curve with free tangents" to match sample offset used in each test
[Added] New test "[Curve] Straight line offset test" in response to pull request feedback.
Update tests/scene/test_curve.h

69f488e687 Property list changes are only notified when it did change in Curve
`Object::notify_property_list_changed()` should only be called when
the structure of the property has actually changed.

The structure of the property tree has not changed if the size of the
array has not changed, and the only possibility is that the element
value has changed.

One Copyright Update to rule them all
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".

adeef12b12 Handle corner cases for curve baking
When control point and point have equal position,
the derivative is 0 vector, which cause error message in Basis::look_at().
This commit handles this case.

91e9ad92f5 Refactor baking code for Curve2D
The main change is to caculate tangent directly from bezier curve, without going
through discretized polyline, avoiding pitfalls of discretization. A similar refacor
had been applied to Curve3D.

The test cases for Curve2D is updated, comparing floating point with is_equal_approxmiate()
instead of `==`, in order to avoid float precision problem.

69f84563a3 Fix Curve3D::get_closest_point() broken
The problem is caused by calling adaptive tessellation baking function by mistake, which produce too few points for straight lines. Calling the even length tessellation fix the problem.

The code for `get_closest_point()` and `get_closest_offset()` are also updated. They used to assume bake interval to be exact, which is no longer true.

The out dated document for `get_closest_point()` is also updated.

f9fa182abc Refactor Curve3D::_bake() method
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;

5241464a46 Refactor Curv3D and PathFollow3D
This commit makes the following major changes

1. Add "sample_baked_with_rotation()" to Curve3D, making it usable independently. A similar change was made to Curve2D previously.
2. Refactor the _bake() method on Curve3D, using Parallel Transport Frame instead of Frenet Frame.
3. Refactor the sample_* methods, including:
  i. Factor out common binary search code, following the DRY principe
  ii. sample_up_vector() interpolated up vector as part of rotation frame(posture) for consistancy and accuracy.

Implement mark_dirty in Curve2D and Curve3D
Implements a method `mark_dirty` in Curve2D and Curve3D like the one
that already exists in Curve, it's a convenient way to set

746dddc067 Replace most uses of Map by HashMap
* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
  (order matters) but use is discouraged.

There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!

8a6fc54ccd Curve2D/Curve3D: exact linear interpolation
While calculating interpolated points, intervals between two baked
points has been assummed to be `baked_interval`. The assumption could
cause significant error in some extreme cases (for example ).

To improve accuracy, `baked_dist_cache` is introduced, which stores
distance from starting point for each baked points. `interpolate_baked`
now returns exact linear-interpolated position along baked points.

6631f66c2a Optimize StringName usage
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.

This is part of ongoing work to optimize GUI and the editor.

Happy new year to the wonderful Godot community!

2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.

We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)

Here's to a great year 2021 for all Godot users 🎆

0ee0fa42e6 Style: Enforce braces around if blocks and loops

07bc4e2f96 Style: Enforce separation line between function definitions
I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
  -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
  -o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```

This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.

This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.

0be6d925dc Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocks
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.

This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.

There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).

94721f5ab8 Revert "Renamed plane's d to distance"
This reverts commit ec7b481170.

This was wrong, `d` is not a distance but the `d` constant in the
parametric equation `ax + by + cz = d` describing the plane.
