XR Camera Subsystem
The camera subsystem is responsible for managing a hardware camera on the AR device. It provides the following data concerning the camera:
- Camera image (as an "external" texture on the GPU).
 - Camera image (as a buffer of bytes available on the CPU).
 - Projection matrix, used to set the field of view and other properties of the virtual camera according to the physical one.
 - Display matrix, used to orient the camera image correctly.
 - Camera intrinsics describing a mathematical model of the camera. Useful for computer vision algorithms.
 - Camera conversion utilities, for converting the CPU image to RGB and grayscale.
 - Light estimation information (color and brightness of the environment).
 - Camera focus mode (i.e., autofocus vs fixed)
