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
The previous name was too strict on what could be put into the effect, and would result in additional clutter in the Filter menu when we eventually decide to support other Upscaling methods than Super-Resolution networks.
