This almost makes my point for why selectable configs are best.  Authors will always want to control priority.  In fact, I suspect authors will want not just single priority flags but rather an ability to give a priority list, e.g., height_bound is more important than best_aspect, which is more important than fit_height, but width_bound, best_fit, and fit_width are unacceptable.

For example, is 176 by 144 bigger or smaller than 160 by 160. What I would propose is that we order them based on the number of pixels. So 176 * 144 = 25344 which is smaller than 160 * 160 = 25600. If the number of pixels is the same then we pick the one that is wider is considered bigger.
