These buttons should help to understand that it is possible to use zoom functionality. It should work well with https://fedorahosted.org/freeipa/ticket/5883. Users will easily understand that scrolling on the canvas doesn't scroll the whole page but only zooms the graph in/out.
Linked to Bugzilla bug: https://bugzilla.redhat.com/show_bug.cgi?id=1298848 (Red Hat Enterprise Linux 7)
