* Add Retro-Tiles shaders A shader designed for handheld and low res systems. It turns pixels into crisp tiles. * Add box scaling - Turn mandatory integer scaling; - Add Overscan option. * Fix gamma on retro-tiles shader - Increased gamma from 2.2 to 2.7 for a better white balance. * Add Gamma Slider to checkerboard-dedither - Add Gamma Slider to checkerboard-dedither. * Update checkerboard-dedither shaders - Add new pattern recognitions; - Add new option to mitigate false positives.
