Description Dan Glastonbury 2022-08-03 22:34:24 PDT

We need to be able to signal a MTLSharedEvent when a command stream has been processed. In order to do this, we'll need an extension to ANGLE that will allow us to pass the MTLSharedEvent down into the ANGLE Metal backend where it can be used.

It's likely that this extension would be specific to Metal, but there is also the chance that other ANGLE backends might want something like this.
