<brief_description>
+ [GLTFDocument] extension class.
</brief_description>
<description>
+ Extends the functionality of the [GLTFDocument] class by allowing you to run arbitrary code at various stages of GLTF import or export.
+ To use, make a new class extending GLTFDocumentExtension, override any methods you need, make an instance of your class, and register it using [method GLTFDocument.register_gltf_document_extension].
+ [b]Note:[/b] Like GLTFDocument itself, all GLTFDocumentExtension classes must be stateless in order to function properly. If you need to store data, use the [code]set_additional_data[/code] and [code]get_additional_data[/code] methods in [GLTFState] or [GLTFNode].
