Comment 2 for bug 1958585

Thanks for the report! I agree that the behaviour should be as you're describing

The code is making some attempt to recenter the view, so I'll have to do some testing with a mouse and look into this. I see one related change in Pinta 2.0 to get Ctrl+wheel working after porting to GTK3 (https://github.com/PintaProject/Pinta/pull/177), so testing against Pinta 1.7 is probably the first place to start
