[GLTFDocument] extension class.

<description>
Extends the functionality of the [GLTFDocument] class by allowing you to run arbitrary code at various stages of GLTF import or export.

The return value is used to determine if this [GLTFDocumentExtension] instance should be used for exporting a given GLTF file. If [constant OK], the export will use this [GLTFDocumentExtension] instance. If not overridden, [constant OK] is returned.

<description>
Part of the import process. This method is run after [method _parse_node_extensions] and before [method _import_post_parse].
Runs when generating a Godot scene node from a GLTFNode. The returned node will be added to the scene tree. Multiple nodes can be generated in this step if they are added as a child of the returned node.

<description>
Part of the import process. This method is run after [method _import_preflight] and before [method _parse_node_extensions].

<description>
Gets additional arbitrary data in this [GLTFNode] instance. This can be used to keep per-node state data in [GLTFDocumentExtension] classes, which is important because they are stateless.
The argument should be the [GLTFDocumentExtension] name (does not have to match the extension name in the GLTF file), and the return value can be anything you set. If nothing was set, the return value is null.

Appends an extension to the list of extensions used by this GLTF file during serialization. If [code]required[/code] is true, the extension will also be added to the list of required extensions. Do not run this in [method GLTFDocumentExtension._export_post], as that stage is too late to add extensions. The final list is sorted alphabetically.
