static_filter (Imlib2::Image)

    /*
     * Apply an Imlib2::Filter (eg a static filter)
     *
     * You should probably using Imlib2::Image#filter() instead, since it is
     * polymorphic (eg, it can handle both static and scripted filters).
     *
     * Example:
     *   filter = Imlib2::Filter.new 20
     *   filter.set 2, 2, Imlib2::Color::GREEN
     *   image.static_filter filter
     *
