Warp Transform doesn't commit changes upon saving the XCF file
Warp Transform follows the same logic that other transform tools follow: if a change is unfinished (Enter wasn't pressed), saving the XCF file will lose the user all unfinished changes.
Given how Warp Transform is sort of brush-based, would it make sense to make it a bit of a special case among transform tools and let it commit changes just like with any brush-based tool?
