remembering the time i was adding a scaler to midboss and i implemented scale2x but instead of doing full equality i added a customizable tolerance for considering pixels equal cause midboss has 32-bit color and a lot of gradients
i realized that this made the scaler work way better and give really nice results with the right threshold set, so i emailed the original creator of the algorithm with my discovery and he basically told me to go away because there were newer, better scalers available and he wasn't interested :|
