(Whiteboard: [fxpe])

I will file blocking bugs for individual pieces of work, but the high-level todos are:

  • Bug 2027951 will have already taken care of building and packaging Metal ANGLE on macOS
  • Need to support IOSurfaces with EGL/ANGLE in SurfacePoolCA and (Render)MacIOSurfaceTextureHostOGL
  • Ensure we use a different EGLDisplay/Metal device for WebGL and Webrender, otherwise we seem to hit threading issues (lots of glitches)
  • Find an alternative to CGLSetVirtualScreen() for GPU switching, for devices with multiple GPUs. (Likely something like "option B" in bug 1600178)
