Modern graphics driver finally have the ability to do integer scaling[1][2], but they only learned that a few years ago. There are also some TVs[3] that can do it, but to my knowledge it's still an extremely rare feature, despite being so simple. Sharp-Bilinear[4] is also worth a mention, this is only available for some emulators, but allows integer-scaling-like quality without being restricted to exact multiple of the resolution.
