2002-12-02 James Henstridge <james@daa.com.au>
* src/thumbnailer.c (main): fix bound on for loop (gaaaargh).
(main): re-enable shutdown of the library
* src/Makefile.am (libfont_method_la_LIBADD): fix typo.
* src/ftstream-vfs.c (FT_New_URI_Face): FT_Stream is a pointer, so
sizeof(FT_Stram) gives the wrong result :(
