Allows clients to implement OpenXR extensions with GDExtension.
</brief_description>
<description>
[OpenXRExtensionWrapperExtension] allows clients to implement OpenXR extensions with GDExtension. The extension should be registered with [method register_extension_wrapper].
Returns a [Dictionary] of OpenXR extensions related to this extension. The [Dictionary] should contain the name of the extension, mapped to a [code]bool *[/code] cast to an integer:
- If the [code]bool *[/code] is a [code]nullptr[/code] this extension is mandatory.
- If the [code]bool *[/code] points to a boolean, the boolean will be updated to [code]true[/code] if the extension is enabled.
Called when there is an OpenXR event to process. When implementing, return [code]true[/code] if the event was handled, return [code]false[/code] otherwise.
Called right before the OpenXR instance is destroyed.

Called as part of the OpenXR process handling. This happens right before general and physics processing steps of the main loop. During this step controller data is queried and made available to game logic.
Allows extensions to register additional controller metadata. This function is called even when the OpenXR API is not constructed as the metadata needs to be available to the editor.
Extensions should also provide metadata regardless of whether they are supported on the host system. The controller data is used to setup action maps for users who may have access to the relevant hardware.
