Now texture storage of images is defined by the alpha mode of the image. The downside of this is that there can be artifacts near alpha edges where pixels with zero alpha bleed in. It also adds more code complexity since image textures are no longer all stored the same way. This changes allows us to keep using sRGB texture formats, which have edge darkening when stored with premultiplied alpha. Game engines seems to generally do the same thing, and we want to be compatible with them.
