Description Dan Glastonbury 2023-06-27 19:05:12 PDT 
There are two paths in WebXROpaqueFramebuffer for attaching compositor provided IOSurface for rendering: 1) Via MTLSharedTexture, and 2) Via pbuffer.

Since it's possible to create a MTLTexture from an IOSurface and plane index, switch away from using pbuffer to reduce the number of code paths.
