	<brief_description>
		Class for importing and exporting glTF files in and out of Godot.
	</brief_description>
	<description>
		GLTFDocument supports reading data from a glTF file, buffer, or Godot scene. This data can then be written to the filesystem, buffer, or used to create a Godot scene.
		All of the data in a GLTF scene is stored in the [GLTFState] class. GLTFDocument processes state objects, but does not contain any scene data itself.
		GLTFDocument can be extended with arbitrary functionality by extending the [GLTFDocumentExtension] class and registering it with GLTFDocument via [method register_gltf_document_extension]. This allows for custom data to be imported and exported.

				Takes a [PackedByteArray] defining a GLTF and imports the data to the given [GLTFState] object through the [param state] parameter.
				[b]Note:[/b] The [param base_path] tells [method append_from_buffer] where to find dependencies and can be empty.

			<description>
				Takes a path to a GLTF file and imports the data at that file path to the given [GLTFState] object through the [param state] parameter.
				[b]Note:[/b] The [param base_path] tells [method append_from_file] where to find dependencies and can be empty.

			<description>
				Takes a [GLTFState] object through the [param state] parameter and returns a GLTF [PackedByteArray].

			<return type="void" />
			<param index="0" name="extension" type="GLTFDocumentExtension" />
			<param index="1" name="first_priority" type="bool" default="false" />
			<description>
				Registers the given [GLTFDocumentExtension] instance with GLTFDocument. If [param first_priority] is true, this extension will be run first. Otherwise, it will be run last.
				[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].

		<method name="unregister_gltf_document_extension" qualifiers="static">
			<return type="void" />
			<param index="0" name="extension" type="GLTFDocumentExtension" />
			<description>
				Unregisters the given [GLTFDocumentExtension] instance.

		<method name="write_to_filesystem">
			<return type="int" enum="Error" />
			<param index="0" name="state" type="GLTFState" />
			<param index="1" name="path" type="String" />
			<description>
				Takes a [GLTFState] object through the [param state] parameter and writes a glTF file to the filesystem.
				[b]Note:[/b] The extension of the glTF file determines if it is a .glb binary file or a .gltf file.
