            Bug ID: 246589
           Summary: [WebXR] Use ANGLE extension to signal compositor
                    completion event
           Product: WebKit
           Version: Other
          Hardware: All
                OS: Other
            Status: NEW
          Severity: Enhancement
          Priority: P2
         Component: WebXR
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: djg at apple.com

Compositors provide an MTLSharedEvent to be signalled at the completion of scene rendering. Now that ANGLE supports signalling external MTLSharedEvent (https://bugs.webkit.org/show_bug.cgi?id=243529), WebXROpaqueFramebuffer rendering should us this to signal when the compositor is free to start composition.
