The async front buffer posting is going to be enabled by another bug. Async IPC was added for async front buffer posting for out-of-process WebGL. Client does not use TextureClient for storing SurfaceDescriptor. It works basically same way as to in-process WebGL around nsDisplayCanvas, WebRenderCanvasData, WebRenderCommandBuilder and WebRenderBridgeParent. SharedSurfaces of SurfaceDescriptorD3D10 are kept alive during their usage. It is for keeping a shread handle valid. Copied data buffers of SharedShurface_Basics are kept alive during their usage. It is for keeping RenderBufferTextureHost valid. Differential Revision: https://phabricator.services.mozilla.com/D150197
