As none of the known Upscaling algorithms handle Alpha, we need to manually restore and interpolate it properly. While this technically reduces visual quality slightly, the chances of this being noticed are slim to none considering that Upscaling is already a questionable solution to quality. Linear was picked here as it produces the best overall result for scaling, keeping gradients mostly in one piece. Mostly. Fixes #646
