drag points to resize i suggest using turbowarp for anything bigger than ~2500 (50x50) pixels (tested without performance mode) https://turbowarp.org/1267535261/
feel free to credit me if you're ever going to use this "performance mode" disables inside fill of the box. quick tutorial: "a" list corresponds to the stage image (yes, it is sadly static). To change it, go to https://xeltalliv.github.io/ScratchTools/Img2list/ and pick the "decimal combined ARGB" mode, then pick your saved stage bitmap; just right click the list and import the text file. credits to apple corporation
