Comment 12 for bug 1958585

The zoom-scroll-wheel branch has been merged (https://github.com/PintaProject/Pinta/commit/32f298e380787dbc81885ea73ab5b058f3a3bbca) with some fixes to be compatible with the GTK4 port

I think the remaining issue is just the jumping around at lower zoom levels because the canvas cannot scroll to stay centered around the zoom point
