Zoom to Cursor

[RednibCoding]

Description
When zooming, it should zoom to the place where the mouse cursor is.

Additional context
The current version of Paint.Net has it:
screen-capture (19).webm

This is how it is in Pinta (zooms to the center):
screen-capture (18).webm

There was a ticket for this on the old launchpad bug tracker which hasn't been migrated over here yet (https://bugs.launchpad.net/pinta/+bug/1958585)
In summary, it's somewhat better in the development builds for Pinta 2.2, but at lower zoom levels it doesn't quite work because the canvas window still only starts scrolling once the image is too large to fit into view
