The native dimensions of the image are scaled by applying the following rules to the `width` and `height` arguments. * If both `width` and `height` are specified, the return value is (`width`, `height`); no scaling is performed. * If only one is specified, it is used to compute a scaling factor that is then applied to the unspecified dimension, preserving the aspect ratio of the image. * If both `width` and `height` are |None|, the native dimensions are returned. The native dimensions are calculated using the dots-per-inch (dpi) value embedded in the image, defaulting to 72 dpi if no value is specified, as is often the case.
