  Message : Expose eglGetMscRateCHROMIUM from EGL_CHROMIUM_sync_control When ANGLE is using the GL backend on GLX, we can expose eglGetMscRateCHROMIUM via glXGetMscRateOML. Otherwise, this function should return false. Bug: chromium:1042393 Change-Id: Id9b308c2217e07ee9860e2869be0e23b7a0c7411 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2017048 Commit-Queue: Jonah Ryan-Davis <jonahr@google.com> Reviewed-by: Geoff Lang <geofflang@chromium.org>
