HandleExternalImage() has two nearly identical code paths for rendering either RenderAndroidSurfaceTextureHost or RenderAndroidHardwareBufferTextureHost using CompositorOGL. The next patch in this series will additionally add support for RenderEGLImageTextureHost. Rather than duplicate the code yet again, we abstract the differences in to a new virtual function RenderTextureHost::CreateTextureSource() and use a single common code path in HandleExternalImage().
