GTK 4.0 Released

I hope eventually I can find the time to contribute some kind of graphics enhancements to ardour. (Maybe this means using GPU acceleration or using a newer GDK version, I don't know) I've noticed scrolling the view can get somewhat laggy on my system when there are a lot of tracks.

We will not be moving to a new version of GDK at any time in the foreseeable future.

The first option seems to be misnamed. When it's disabled it will cache the canvas widgets in cairo surfaces, but it will still use CPU blitting when it actually copies the image back to the window.

I couldn't find the second option, even grepping for it in git master.
