Dario 47214ea9f5 Optimize lightmapper using triangle clusters on the acceleration structure.
Add an additional layer of indirection to the grid used by the lightmapper to store fixed-size triangle clusters. Greatly speeds up baking times on scenes with high triangle density, as the clusters will help to avoid unnecessary checks when the triangle density is high on the scene.

Dario a9a197d2dc Rewrite the GPU Lightmapper's indirect lighting logic to match Godot 3.5's CPU Lightmapper.
Port over the logic from Godot 3.5 for indirect lighting. This should fix many issues about indirect bounces causing more energy and improve the overall quality of the result.

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".

clayjohn 385ee5c70b Implement Physical Light Units as an optional setting.
This allows light sources to be specified in physical light units in addition to the regular energy multiplier. In order to avoid loss of precision at high values, brightness values are premultiplied by an exposure normalization value.

In support of Physical Light Units this PR also renames CameraEffects to CameraAttributes.

Adds `header_guards.sh` bash script, used in CI to validate future
changes. Can be run locally to fix invalid header guards.

reduz 141c375581 Clean up Hash Functions
Clean up and do fixes to hash functions and newly introduced murmur3 hashes in #61934
* Clean up usage of murmur3
* Fixed usages of binary murmur3 on floats (this is invalid)
* Changed DJB2 to use xor (which seems to be better)

clang-format: Disable alignment of operands, too unreliable
Sets `AlignOperands` to `DontAlign`.

`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.

William Deurwaarder a7599076d2 GPULightmapper: execute dilate before denoise
Dilate fills gaps that are caused by the rasterization. Previously denoise
was done before dilate which caused the gaps to become filled (non-zero). This
resulted that the gaps were not recognized by
dilate  and the background color leaked.

This is fixed by executing dilate before denoise.

William Deurwaarder e11dd6500a GPULightmapper's triangles and their bounding box will be in-sync
Previously the bounding boxes and triangles were maintained in two separate
arrays (Vectors). As the triangle vector was sorted and the bounding-box array
was not , the order of both arrays differed. This meant that the index in one
was different than the other, which caused lookup issues.

To prevent this, the bounding-box is now part of the triangle structure so that
there is a single structure that cannot become out-of-sync anymore.

jfons 6995b0429c Assorted fixes to UV unwrapping and GPU lightmapper
Various fixes to UV2 unwrapping and the GPU lightmapper. Listed here for
context in case of git blame/bisect:

* Fix UV2 unwrapping on import, also cleaned up the unwrap cache code.
* Fix saving of RGBA images in EXR format.
* Fixes to the GPU lightmapper:
	- Added padding between atlas elements, avoids bleeding.
	- Remove old SDF generation code.
	- Fix baked attenuation for Omni/Spot lights.
	- Fix baking of material properties onto UV2 (wireframe was
	  wrongly used before).
	- Disable statically baked lights for objects that have a
	  lightmap texture to avoid applying the same light twice.
	- Fix lightmap pairing in RendererSceneCull.
	- Fix UV2 array generated from `RenderingServer::mesh_surface_get_arrays()`.
	- Port autoexposure fix for OIDN from 3.x.
	- Save debug textures as EXR when using floating point format.

jfons 99e1ce0690 Invert spotlight angle attenuation
Inverted the spotlight angle attenuation so a higher value results in
a dimmer light, this makes it more consistent with the distance
attenuation.

Also changed the way spotlighs are computed in SDFGI
and GIPorbes and GPU lightmapper, now it matches the falloff used in the scene rendering
code.

Update copyright statements to 2021
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 🎆

Rémi Verschelde 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).

Part of #33027.

Juan Linietsky 1bea8e1eac New lightmapper
-Added LocalVector (needed it)
-Added stb_rect_pack (It's pretty cool, we could probably use it for other stuff too)
-Fixes and changes all around the place
-Added library for 128 bits fixed point (required for Delaunay3D)
