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.
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 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.

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.
