Adds a new system to automatically reorder commands, perform layout transitions and insert synchronization barriers based on the commands issued to RenderingDevice.
A new `Math::division_round_up()` function was added, allowing for easy
and correct computation of integer divisions when the result needs to
be rounded up.
Fixes#80358.

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.
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.
The DDA traversal had a conceptual error where it did an early termination of the search if it hit a triangle, but it didn't check if the hit position was inside the bounds of the cell being traversed. This can aid to fix light leaks such as the ones found in issue #75440.
This is consistent with `xatlas_unwrap`, which isn't enabled in non-editor
builds and the Android editor either. There is currently no way to
use the lightmapper in a non-editor build anyway, as it doesn't expose
any methods (and even if there was, there would be no way to perform
UV2 unwrapping in the exported project).
This reduces binary size of a stripped Linux x86_64 export template
build by ~164 KB.
This also moves the PrimitiveMesh texel size project setting
so that it's defined when the module is disabled,
and adds a property hint to it.
The brightness now matches dynamic lights (indirect light baked only)
when Directional is enabled.

Add half-pixel offset to lightmapper to fix issues where the ray would be generated from the wrong spot corresponding to the pixel and causing light leaks. Fixes Issue #69126.
This applies our existing style guide, and adds a new rule to that style
guide for modular components such as platform ports and modules:
Includes from the platform port or module ("local" includes) should be listed
first in their own block using relative paths, before Godot's "core" includes
which use "absolute" (project folder relative) paths, and finally thirdparty
includes.
Includes in `#ifdef`s come after their relevant section, i.e. the overall
structure is:
- Local includes
* Conditional local includes
- Core includes
* Conditional core includes
- Thirdparty includes
* Conditional thirdparty includes
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".
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.
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)
* Changed to use the same stages as extensions.
* Makes the initialization more coherent, helping solve problems due to lack of stages.
* Makes it easier to port between module and extension.
* removed the DRIVER initialization level (no longer needed).
* Changed syntax usage for RD::Uniform to create faster with a single RID
* Converted render pass setup to use this in clustered renderer to test.
This is the first step into creating a proper uniform set cache system to simplify large parts of the codebase.
Previous algorithm used an algorithm to generate rays that was not completely
random. This caused artifacts when large lighmap textures were used.
The new algorithm creates better rays and by that prevents artifacts.
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`.
Dilate fills gaps that are caused by the rasterization. As dilate is based on
the alpha-channel which is not part of denoise, dilate can be run after denoise
as well. So that colors are not denoised/mixed over seams.
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.
Currently the method ray_hits_triangle determines triangles not to be hit by
a ray due to an epsilon that is too big. In practice those triangles are hit by
those rays.
This is fixed by introducing a smaller epsilon.
In case the calculation of the delta contained infinity values (division by
zero), than later the calculation of the next cell failed as the infinity value
was multiplied by zero which resulted in a nan. The nan-value caused that the
next cell was equal to the current cell which resulted in an end-less loop,
which only terminates by the maximum iterations protection.
This is solved by replacing infinity with grid_size which acts as infinity.
Before this change only rays to the sky (RAY_MISS) in the first bounce were
processed as active rays. This caused artifacts, areas were too light, when
more than one bounce were processed.
Now rays to the sky are processed as active rays for all bounces.
Smoothening positions for flat, non-smoothened, triangles is unnecessary and
caused positions to move outside their triangle which caused side-effects as
rays from those positions intersected with triangles which could not be
reached from the original triangle.
This is solved by skipping smoothening of positions for flat triangles.
A triangle is determined to be flas as its vertex normals are equal.
Edges that are at the edge of a plane, may get behind the scene and will hit
back-face triangles which where included in the lighting calculations. This
caused leaking of light at the edge of planes.
In case a ray hits back-face triangle, it is skipped in the bounce calculations.
