Not exactly the same, but similar: when working with sprites for games, I often run into situations where I realize way too late that I need the size of each frame to be slightly larger than what I had been working with it. You’d think that having the ability to resize an image by adding extra padding to each individual frame would be a pretty common feature in image editing software these days, but nope. I ended up writing a small tool specifically for that just so I wouldn’t have to adjust frame by frame ever again.
