One note here, when running a wayland spice-gtk/remote-viewer, the only
scroll events I'm getting are GDK_SCROLL_SMOOTH events, I'm not getting
any scroll event until I add GDK_SMOOTH_SCROLL_MASK to the events
spice-gtk listens to (which results in the mouse wheel not being
functional with a wayland client).
