Passing `-msse2` doesn't seem to be sufficient to opt into SSE floating point math
instead of the less stable x87.
`-mstackrealign` also seems necessary when using SSE on x86_32.
Setting it only for release templates on Windows and macOS was inconsistent,
and Jolt requires it as a minimum.
Drop the `-mxsave` flag from the raycast module, this doesn't seem to be
used explicitly by Embree, and unnecessarily makes our config and baseline
muddy.
Due to the low resolution of the occlusion buffer, small gaps between occluders can be closed and incorrectly occlude instances which should show through the gaps. To ameliorate this problem, this PR jitters the occlusion buffer over time, making it more likely an instance will be seen through a gap. This is used in conjunction with an occlusion timer per instance, to prevent instances flickering on and off rapidly.
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".
The commit b5a8055b5c should target GCC builds only as
-flax-vector-conversions has different behaviour in Clang and is
currently making the build fail.

This is a change done upstream in the `devel3` branch for 3.13.6:

They also seem to define it for macOS, but for us it breaks the build...
¯\_(ツ)_/¯
Also change wrong use of CPPFLAGS (pre-processor) where CXXFLAGS (C++)
makes more sense.
Embree initially only supported x86_64, then got arm64 support added.
Now it seems to be possible to build it with Emscripten (wasm32) and
on x86_32 Windows.
- `_DEBUG` is MSVC specific so it didn't make much sense to define for
Android and iOS builds.
- iOS was the only platform to define `DEBUG`. We don't use it anywhere
outside thirdparty code, which we usually don't intend to debug, so it
seems better to be consistent with other platforms.
- Consistently define `NDEBUG` to disable assert behavior in both `release`
and `release_debug` targets. This used to be set for `release` for all
platforms, and `release_debug` for Android and iOS only.
- Due to the above, I removed the only use we made of `assert()` in Godot
code, which was only implemented for Unix anyway, should have been
`DEV_ENABLED`, and is in PoolAllocator which we don't actually use.
- The denoise and recast modules keep defining `NDEBUG` even for the `debug`
target as we don't want OIDN and Embree asserting all over the place.
