        * rsvg-cairo.h: Make cairo render functions return a gboolean. Returns TRUE
        if the image can't be rendered
        * rsvg.c: Check && handle the return value
        * rsvg-cairo-render.c: Implement the above. Also, return FALSE if we're asked
        to render an ID that doesn't exist

        Collectively, fixes #540383 - rsvg_handle_render_cairo_sub - if ID not found,
        return an error and/or dont render whole SVG
