I wonder if we even need a WebGL1 code path... |
AFAIK, yes 😇 . |
|
WebGL 1.0 WebXR-related code paths can probably be safely removed once WebGL 2.0 is enabled by default on Safari/iOS devices, to prevent the unlikely scenario of WebXR support landing (looks like it's close) and WebGL 1.0 still being the default. It seems likely that those two would ship together though. |

I doubt WebXR will land in Safari any time soon... |

Description
The change switches more code away from the old style WebXRLayer by relying on WebGL2 MSAA support.
I carefully coded this to avoid flushes of the AA data to main memory so it's just as fast as before.
I did notice that other parts of three.js are causing flushes. I will debug those separately.
