Bug 1486659 - p3: copy texture contents for remote allocated Surface. r=snorp Child processes cannot access textures allocated in the parent process, which is needed by the compositor to render video elements efficiently. Unfortunately, Android doesn't expose Sufrace buffers (sharable across processes) in the SDK/NDK as other platforms, so we need to generate extra texture/surface in the child process and update texture images through the surface, which is passed to the parent process for the remote texture to copy its contents into.
