[Werner Lemberg]

annotated tag: VER-2-13-1
commit 73c2159b52912d0882401fdd196f9fd55529a7e7
Author: Hin-Tak Leung <htl10@users.sourceforge.net>
Commit: Werner Lemberg <wl@gnu.org>

    Fix 'librsvg' deprecation warnings.
    
    * src/rsvg-port.c (rsvg_port_preset_slot): Use `rsvg_handle_render_document`
    instead of `rsvg_handle_render_cairo`, and `rsvg_handle_render_layer`
    instead of `rsvg_handle_render_cairo_sub`, as suggested by the warning,
    conditionally on newer librsvg 2.52+.
