//       Class : TextureReloadRequest
// Description : This loader request will call
//               Texture::get_ram_image() in a sub-thread, to force
//               the texture's image to be re-read from disk.  It is
//               used by GraphicsStateGuardian::async_reload_texture(),
//               when get_incomplete_render() is true.
