	    Bug 2673 - Need to hook up the new font picker to nautilus .

	    * configure.in:
	    Remove an old font setup hack that never really worked.

	    * data/fonts/urw/fonts.dir:
	    Rename the fonts to "Helvetica Default" in order not to clash with
	    system fonts.

	    * libnautilus-extensions/nautilus-font-manager.h:
	    * libnautilus-extensions/nautilus-font-manager.c:
	    (font_description_new): Add a font type parameter.
	    (font_lists_total_num_fonts): New function to count the total
	    number of scalable fonts detetected.
	    (font_description_table_add): Pass in the detected font lists to
	    do reality checks.
	    (font_get_font_type): New function.
	    (font_description_table_get_length),
	    (font_description_table_peek_nth),
	    (font_description_table_get_nth_file_name): Name the parameters
	    more consistently.
	    (font_description_table_for_each): Add font type parameter
	    (font_description_table_new): Rework to not require storing the
	    detected font list.  We now use that only for the duration of the
	    constructor.  Lost the install_font_lists dumbness.
	    (font_server_for_each_font_directory_internal): Use g_warning
	    instead of g_print.
	    (font_ignore_directory): New function to determine whether we
	    should ignore a directory - makes things much faster.
	    (font_manager_collect_font_tables): New function to handle all the
	    work of collecting font directories into tables.
	    (font_server_for_each_callback), (font_table_list_free),
	    (font_table_list_for_each), (free_font_tables),

	    tables for fallback, system and users fonts.  These are populated
	    as needed.
	    (nautilus_font_manager_for_each_font): Iterate the 3 font talbles.
	    (nautilus_font_manager_get_fallback_font) : New function to obtain
	    a fallback font quickly without having to check the system.
	    (call_chop_off_comments), (nautilus_self_check_font_manager):
	    Rework the checks to not create a temp directory.  Unfortunately
	    they now only run for me.
