Author: Werner Lemberg <wl@gnu.org>
Commit: Werner Lemberg <wl@gnu.org>

    Fix clang++ warnings.
    
    * src/base/ftglyph.c (ft_svg_glyph_prepare), src/base/ftobj.c
    (ft_glyphslot_init), src/cache/ftccmap.c (ftc_cmap_node_new),
    src/cache/ftcimage.c (FTC_INode_New), src/lzw/ftlzw.c (FT_Stream_OpenLZW),
    src/psaux/psobjs.c (ps_parser_load_field), src/pshinter/pshglob.c
    (psh_globals_new), src/sfnt/ttsvg.c (tt_face_load_svg_doc): Initialize
    variables used for allocation.
    
    * src/sdf/ftsdf.c (split_sdf_conic, split_sdf_cubic): Change type of
    `max_splits` to FT_UInt.
    (sdf_generate_bounding_box): Add cast.
