1) make RenderTextureHost into a abstract base class for all RenderXXXTextureHost. 2) create a base class RenderTextureHostOGL for all texture handle base texture. 3) create RenderBufferTextureHost for buffer texture at render thread. 4) create RenderMacIOSurfaceTextureHostOGL for MacIOSurface at render thread.
