Fix tiny window when resetting zoom factor in gtk2 build

Browse Source 
rhbz#1104064 had a couple of symptoms. The first was fixed in
6edde57862.

The second symptom is that displays could also become tiny when clicking 'View >
Zoom > Normal Size'. This was because VirtViewerDisplay returned early from
_display_set_zoom_level() if the zoom level was being set to the current zoom
setting. However, the calling function (_window_set_zoom_level()) also tries to
queue a resize event for itself after setting the zoom level on the display. If
the display doesn't queue a resize event for itself, its size request will only
be 50x50 during the window resize negotiation. This causes the display to become
tiny and zoomed out. Queueing a resize on the display widget ensures that it
will request the proper size during the next allocation.
