* RenderTextureHost of GPUVideoTextureHost.

* GPUVideoTextureHost wraps TextureHost. This class wraps RenderTextureHost of
* the wrapped TextureHost. Lifetime of the wrapped TextureHost is usually
* longer than GPUVideoTextureHost and the wrapped TextureHost is used by
* multiple GPUVideoTextureHosts. This class is used to reduce recreations of
* the wrappded RenderTextureHost. Initializations of some
* RenderTextureHosts(RenderDXGITextureHost and
* RenderDXGIYCbCrTextureHost) have overhead.
