- GLBs produced by godot don't pass validation when there's no data in the buffer segment. The segment is dropped but the size of the chunk_header is still reported in total length (incorrectly)
- Remove empty "extensions" JSON object being appended to all nodes (if it's still empty). This is just cutting down on unnecessary bloat and consistent with the rest of the file's attempts to not emit any keys that are equal to their default value.
- Allow the case where root_nodes is empty. This is permitted by the GLTF spec. Moreover it can happen fairly naturally when using the ROOT_NODE_MODE_MULTI_ROOT root node mode on a scene with only a root node (which is valid in godot).
- Don't create an initial buffer until we're ready to write data into it (buffers of byteLength=0 don't pass validation).
* Replaces `find(...) != -1` with `contains` for `String`
* Replaces `find(...) == -1` with `!contains` for `String`
* Replaces `find(...) != -1` with `has` for containers
* Replaces `find(...) == -1` with `!has` for containers
Set p_scene_parent to the skeleton to guarantee BoneAttachment3D nodes are added as a child of the active skeleton.
Use get_owner() to go all the way up when calculating the root node in generate_scene
Adds a bool import option `nodes/import_as_skeleton_bones`.
This is supported in all FBX or GLTF document based formats.
It is especially useful for retargeting and importing animations.
This update introduces a new import method for FBX files using ufbx. If the fbx2gltf import fails, it will use the most recently cached scene from the ufbx import. The process is sped up by introducing threads to load the ufbx portion.
Key changes include:
- Support for importing geometry helper nodes in FBX files.
- Addition of cameras and lights with updated names.
- Removal of the fbx importer manager.
- Introduction of ModelDocument3D and updates to its methods.
- Changes to FBX import options and visibility.
- Updating the documentation and handling some errors.
- Store the original non-unique node, mesh and animation names in FBX and glTF.

Currently all object transform animation tracks get imported and baked
as linear. For step interpolation mark the resulting animation track
with Nearest interpolation to make sure there are no in-betweens
generated. This is useful for camera cuts or similar.
1. Extracted texture paths in `GLTFDocument::_parse_image_save_image` at the project root started with res:/// which broke cache invalidation
2. md5 hashes were not being written to generator_parameters for new imports, which led Godot to think the file was manually created.
3. `EditorFileSystem::reimport_append` must emit the `resources_reimported` signal in order for the resource cache to be updated.
Ensure `ensure_tangents` option actually creates tangent array. Even if it is just a dummy array.
Allow mesh to generate its own tangents when using compression. This allows users to compress meshes without tangents.
Warn users if they are trying to read from tangents without providing tangents.
