    ev-view.c: ignore unintended motion events while launching synctex
    
    Synctex is launched by a Ctrl+leftClick, but sometimes if we move
    mouse slightly when doing the click an unwanted  motion event is
    generated which will trigger a "extend text selection" action
    (because we have CTRL modifier pressed) and this happens just
    before we focus out of Evince, causing the symptoms described in
    Issue #951.
    
    Closes #951
