    (#390): Increment library version number
    
    The 2.45 series added rsvg_handle_get_geometry_sub().
    
    We won't remove/change existing interfaces in this series; just
    additions for now.  All changes/removals will happen in the 3.0
    series.
    
    Fixes https://gitlab.gnome.org/GNOME/librsvg/issues/390
