An xBR implementation within Aseprite's scripting environment!
This extension was commissioned by Raindrinker on Twitter. Thank you so much!
xBR is a pixel art scaling algorithm originally by Hyllian. Since then, there have been many implementations. I have referenced others' work and transposed these algorithms into Lua, as well as tied into the Aseprite Scripting API. I am truly standing on the shoulders of giants for this extension.
