Message : GL: Add extensions to enable hardware video decode on Android. The Android SurfaceTexture API has to be initialized with a texture id which Chrome has to query from an ANGLE external texture. It also rebinds and sets the texture dimensions on calls to SurfaceTexture.updateTexImage so ANGLE must be notified about these changes so that state tracking and validation continue to function. BUG=967410 Change-Id: I92e9077f75835b088da3a8caffb3ff40e9ad0361 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1630293 Commit-Queue: Geoff Lang <geofflang@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
