+ * 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.
