The zoom capability was added by a user who wanted the ability to have
multiple virt-viewer windows open, but zoomed out so the windows were
like 1/4 normal size. eg presenting more of a "live thumbnail" view
of the guest.
Zoom mode + scaling can work in co-ordination with each other. eg if
your have 2:1 zoom, and you resize the window to 800x600, then the
guest resolution should change to be 1600x1200, since the windows is
displaying 50% reduction. This certainly used to work correctly, so
if it doesn't anymore that would be a regression.
