Meta class registering supported devices in OpenXR. This class allows OpenXR core and extensions to register metadata relating to supported interaction devices such as controllers, trackers, haptic devices, etc. It is primarily used by the action map editor and to sanitize any action map by removing extension-dependent entries when applicable. Registers an interaction profile using its OpenXR designation (e.g. [code]/interaction_profiles/khr/simple_controller[/code] is the profile for OpenXR's simple controller profile). [param display_name] is the description shown to the user. [param openxr_path] is the interaction profile path being registered. [param openxr_extension_name] optionally restricts this profile to the given extension being enabled/available. If the extension is not available, the profile and all related entries used in an action map are filtered out. Registers an input/output path for the given [param interaction_profile]. The profile should previously have been registered using [method register_interaction_profile]. [param display_name] is the description shown to the user. [param toplevel_path] specifies the bind path this input/output can be bound to (e.g. [code]/user/hand/left[/code] or [code]/user/hand/right[/code]). [param openxr_path] is the action input/output being registered (e.g. [code]/user/hand/left/input/aim/pose[/code]). [param openxr_extension_name] restricts this input/output to an enabled/available extension, this doesn't need to repeat the extension on the profile but relates to overlapping extension (e.g. [code]XR_EXT_palm_pose[/code] that introduces [code]…/input/palm_ext/pose[/code] input paths). [param action_type] defines the type of input or output provided by OpenXR. Registers a top level path to which profiles can be bound. For instance [code]/user/hand/left[/code] refers to the bind point for the player's left hand. Extensions can register additional top level paths, for instance a haptic vest extension might register [code]/user/body/vest[/code]. [param display_name] is the name shown to the user. [param openxr_path] is the top level path being registered. [param openxr_extension_name] is optional and ensures the top level path is only used if the specified extension is available/enabled. When a top level path ends up being bound by OpenXR, a [XRPositionalTracker] is instantiated to manage the state of the device.
