    win32: Remove extraneous changes
    
    Commit 6ae30826033 included some changes from the gtk-3-24 branch that
    do not make sense in the context of the commit, and break the build of
    GTK 2 on Windows. The delta_x and delta_y fields do not exist in the
    GdkEventScroll in the gtk-2-24 branch.
