Support zoom via touchpad scrolling
I noticed when I am under Wayland the touchpad vertical scrolling (Up & Down) does not zoom-in or zoom-out the image.
While, when I am under X11, it works fine.
Clarification 1: touchpad horizontal (Left & Right) scrolling works well, showing next/previous
Clarification 2: touchpad gesture for rotation works under both windowing system
Same issue here [eog#168] for EOG...
Tried on Arch Linux w/ Loupe 44.2 GNOME 44
