Reland "ANGLE_platform_angle_device_context_volatile_* extensions" This is a reland of e70f6aa679dd72eca5c88c71b0932928e92d6067 Original change's description: > ANGLE_platform_angle_device_context_volatile_* extensions > > Change from Kimmo Kinnunen downstream: > https://bugs.webkit.org/show_bug.cgi?id=216106 > > Add two extensions for EAGL and CGL backends to declare the > underlying platform context being "volatile". It means that > the thread-global current context is being modified behind > ANGLE. If ANGLE context is marked volatile for a particular > API, it will sync the underlying context for every EGL > function that needs the context. Most intuitive use is > for the client to call eglMakeCurrent before calling any > gl function if the client knowns the platform state might > be dirty. > > Implement eglReleaseThread for EAGL and CGL backends. > Releasing thread will unset the platform current context. > > Fix a bug of omitting EGL_ANGLE_device_eagl from being > advertised. > > Bug: angleproject:5104 > Change-Id: I1ec98ad35bc0caada23556ae8697fdef20f65b1a > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2486548 > Commit-Queue: James Darpinian <jdarpinian@chromium.org> > Reviewed-by: Kenneth Russell <kbr@chromium.org> > Reviewed-by: Geoff Lang <geofflang@chromium.org> Bug: angleproject:5104 Change-Id: I88265625a4bb4c1412532768d17d7b4356c7be41 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2508842 Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: James Darpinian <jdarpinian@chromium.org>
