* @code{c}
* original_width = tile->width + bound_left + bound_right;
* original_height = tile->height + bound_top + bound_bottom;
* @endcode

* @note These values are valid only for the tiled equirectangular
* projection type (@ref AV_SPHERICAL_EQUIRECTANGULAR_TILE),
* and should be ignored in all other cases.
