Solving wishlist item at
https://bugs.launchpad.net/qemu/+bug/1656710
by accepting Ctrl-Alt-= as an additional zoom-in acceleration.
Using gtk_accel_group_connect to support multiple accelerations
triggering a single menu item since that gtk_accel_map_add_entry
seems to support only one acceleration. A wrapper function
gd_accel_zoom_in is added to support gtk_accel_group_connect's
callback activities.
