Makes it easy to use an alternate form of window scaling that better preserves the apparent pixel sizing.Includes a bilinear filtering shader and a scene that uses it for window scaling. This prevents variations in pixel sizes at resolutions that can't be divided perfectly, while keeping pixels well defined. Especially useful for pixel art games.
Emulator-style pixel upscaling algorithm. Ported from the SameBoy to Godot 3+. Works similarly to hqx at arbitrary precision.
