Replace mesh generator with compute_distortion function on xrt_device. This is used to both make it possible to use mesh shaders for devices and to provide compatibility with SteamVR which requires a compute_distortion function as well.

The compositor uses this function automatically to create a mesh and uses mesh distortion for all drivers. The function compute_distortion default implementations for none, panotools and vive distortion models are provided in util.
