This class encapulsates several extension methods that help convert between the Quest's coordinate system and Unity's coorindate system. Use these methods to convert to and from the Quest's local tracking space and Unity's world space, for example.

This class also contains several methods to facilitate native interop, as the native plugin uses a different coordinate system than Unity (for example, OVRPlugin.Posef). These methods are used by the Meta XR Core SDK, but typically should not necessary in application code.
