This allows Godot to automatically compress meshes to save a lot of bandwidth.
In general, this requires no interaction from the user and should result in
no noticable quality loss.
This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.
Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.
Fixes#76338.
Blender 3.6 imports fail with:
```
TypeError: Converting py args to operator properties: : keyword "export_nla_strips" unrecognized
```
The `export_nla_strips` flag was removed and replaced with `export_animation_mode`.
In 3.6.0-3.6.21, this option does not exist at all and causes the failure above.
In 3.6.22, this option was re-added, but does nothing.
See 96a73cb664.
We now need to check the blender version to determine what flags to use.
This adds an additional shell command before every import.
We might consider caching the version, but we'd have to invalidate the cache if the blender version or path changes.
As an aside, the "group animations" setting in Godot does the opposite of what I'd expect.
When `group_tracks=true`, each animation is exported individually.
When `group_tracks=false`, all animations are exported as a single track.
This seems backwards, but I've kept the 3.6 behavior consistent with 3.5.
From https://docs.blender.org/api/3.6/bpy.ops.export_scene.html:
> ACTIONS Actions – Export actions (actives and on NLA tracks) as separate animations.
> ACTIVE_ACTIONS Active actions merged – All the currently assigned actions become one glTF animation.

The importer already checks if a mesh has vertex colors and enables
vertex colors on the material using it.
Before this fix, GLTF importer would force shader generation to use
vertex colors even if the scene did not have vertex colors at all, or
did not need them; causing inefficient shader and PSO generation.
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).
This reads the multiplier for the emission strength from GLTF files.
This is fairly universal and is required for blender's emission value to be imported.
The value is a simple universal multiplier and is unitless.

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
- Simplify and update its logic.
- Simplify EditorScript.
- Improve EditorNode and other relevant includes.
- Fix scene-based path in the movie writer when
reloading a scene.
Also start organizing editor-specific GUI components
into a dedicated folder, `editor/gui`.
Also move `editor_file_server` next to the rest of debugger classes.
When using custom color management in blender the --version command will
output additional information infront of the "normal" output and this
prevented the import.
Fixes#74439.
Pretty hacky solution but it's better than an infinite loop.
All this import setup needs to be redone, it's very difficult to properly
bail out from an invalid import without triggering reimport loops.
Also fix underline not visible at default editor scale in LinkButton.
Fixes#73319.
- If RPC import fails, then try a direct import as well. While it's
slower, it may be better than failing the import completely.
- Connection errors will disable RPC automatically, to avoid having to
wait the full 30 seconds timeout each time.
This should be properly fixed by allowing to override the timeout
per HTTPClient.
This option allows for a safe fallback for embedded gltf textures in cases where VRAM compression is not needed.
Add an is_editor_hint guard around GLTFHandleBinary::HANDLE_BINARY_EXTRACT_TEXTURES, to use EMBED_AS_UNCOMPRESSED by default at runtime.
This provides an option for pixel art to be stored losslessly.
Additionally, respect project importer defaults for texture import settings.
Avoid writing and reimporting extracted textures identical to version on disk.
[ Ignore and Warn | Extract Textures (default) | Optimize Loading Embedded as Basisu ]
Enable compressed mip maps from Basis Universal for faster compressions.
Increase the quality of Basis to avoid corruption.
To keep compatibility use the first mip of the previous internal Godot format.
Because texture names may have invalid filename characters, adds String::validate_filename to sanitize filenames for import pipeline use.
BoneAttachment3D nodes are now named as their bone name.
Resolves cases where BoneAttachment3D nodes will have arbitrary names like BoneAttachment3D6
Reserve the name "Skeleton3D" and use this name for all generated Skeleton3D nodes.
This change will break existing imported scenes with more than one skeleton and/or bone attachments.
Recursively adds child nodes into each skeleton. This should prevent nested skeletons and avoid bone attachments for leaf bones.
In cases where a skinned mesh has children, creates two scene nodes with the same name, which both will represent this single gltf node.
Because blend shape animations must target the mesh, adds a separate mapping for ImporterMeshInstance3D node references.
This change will break existing imported scenes with bone attachments and more than one skeleton.

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".
* If FBX files are found, a dialog will pop up asking to configure FBX2glTF.
* Dialog can also be accessed by going Editor -> Configure FBX Import.
* The dialog also shows a link to click to download the converter, which
should contain instructions.
This improves performance when importing many Blender files, as it
avoids waiting for Blender to startup every time.
Old logic is still available by setting the RPC port setting to 0.
Add support for font weight and stretch selection when using system fonts.
Add function to get system fallback font from a font name, style, text, and language code.
Implement system font support for Android.
Use system fonts as a last resort fallback.
Replace all TODO uses of `#warning` by proper TODO comments, and will open
matching bug reports to keep track of them.
We don't have a great track record fixing TODOs, but I'd wager we're even
worse for fixing these "TODO #warning" so we should prohibit this usage.
Implements https://github.com/godotengine/godot-proposals/issues/3371.
New `target` presets
====================
The `tools` option is removed and `target` changes to use three new presets,
which match the builds users are familiar with. These targets control the
default optimization level and enable editor-specific and debugging code:
- `editor`: Replaces `tools=yes target=release_debug`.
* Defines: `TOOLS_ENABLED`, `DEBUG_ENABLED`, `-O2`/`/O2`
- `template_debug`: Replaces `tools=no target=release_debug`.
* Defines: `DEBUG_ENABLED`, `-O2`/`/O2`
- `template_release`: Replaces `tools=no target=release`.
* Defines: `-O3`/`/O2`
New `dev_build` option
======================
The previous `target=debug` is now replaced by a separate `dev_build=yes`
option, which can be used in combination with either of the three targets,
and changes the following:
- `dev_build`: Defines `DEV_ENABLED`, disables optimization (`-O0`/`/0d`),
enables generating debug symbols, does not define `NDEBUG` so `assert()`
works in thirdparty libraries, adds a `.dev` suffix to the binary name.
Note: Unlike previously, `dev_build` defaults to off so that users who
compile Godot from source get an optimized and small build by default.
Engine contributors should now set `dev_build=yes` in their build scripts or
IDE configuration manually.
Changed binary names
====================
The name of generated binaries and object files are changed too, to follow
this format:
`godot.<platform>.<target>[.dev][.double].<arch>[.<extra_suffix>][.<ext>]`
For example:
- `godot.linuxbsd.editor.dev.arm64`
- `godot.windows.template_release.double.x86_64.mono.exe`
Be sure to update your links/scripts/IDE config accordingly.
More flexible `optimize` and `debug_symbols` options
====================================================
The optimization level and whether to generate debug symbols can be further
specified with the `optimize` and `debug_symbols` options. So the default
values listed above for the various `target` and `dev_build` combinations
are indicative and can be replaced when compiling, e.g.:
`scons p=linuxbsd target=template_debug dev_build=yes optimize=debug`
will make a "debug" export template with dev-only code enabled, `-Og`
optimization level for GCC/Clang, and debug symbols. Perfect for debugging
complex crashes at runtime in an exported project.
- Don't warn about minimized/maximized modes not being available.
- Blender and FBX export both depend on running thirdparty applications,
which can't be done (easily at least) for Web and Android editors.
- Editor theme complained about not being able to retrieve texture data
for an icon. It was only used once so instead of flipping at runtime,
let's just add a flipped icon.
