	Rewrite a lot of the output drivers and infrastructure.
	Started transitioning from msg() to error().
	Vertical rules in tables now default to putting a small gap
	between columns, instead of no gap or rule at all.
	See NEWS for user-visible changes.

	* automake.mk: (output_sources) Add afm.c, afm.h.  Remove font.h,
	groff-font.c.
	
	* afm.c, afm.h: New files.

	* font.h: Removed.

	* groff-font.c: Removed.
	
	* ascii.c: Rewrote and simplified.

	* html.c: Ditto.

	* postscript.c: Ditto.

	* output.c: (struct outp_driver_class_list) Move here from
	output.h.  Remove ref_count member and all references to it.
	(outp_init) Remove epsf_class references.
	(init_default_drivers) Use new configure_driver_line() interface.
	(parse_options) Renamed outp_parse_options(), changed interface.
	(configure_driver) Changed args from `const char *'s to `const
	struct string *'s.  Rewrote.  Don't call ->open_global().  Now
	just calls ->open_driver() instead of ->preopen_driver(),
	->option(), ->postopen_driver().
	(configure_driver_line) Adapt to new configure_driver() interface.
	(destroy_driver) Don't call ->close_global().
	(option_cmp) Removed.
	(outp_match_keyword) Rewrite for simplicity.
	(outp_open_page) New function.  Changed all equivalent
	functionality to use this function instead.
	(outp_close_page) Ditto.
	(outp_eject_page) Use above functions.
	(outp_string_width) Add font argument and change all callers to
	pass one.

	* output.h: (struct rect) Removed.
	(OUTP_L_*) Name this enumeration "enum outp_line_style".
	(OUTP_L_SPECIAL) Removed.
	(struct color) Removed.
	(OUTP_F_*) Removed.
	(struct outp_styles) Removed.
	(OUTP_T_*) Removed.
	(enum outp_justification) New, containing OUTP_RIGHT, OUTP_LEFT,
	OUTP_CENTER.
	(enum outp_font) New, containing OUTP_FIXED, OUTP_PROPORTIONAL,
	and OUTP_EMPHASIS.
	(struct outp_text) Replaced `options' member by `font' and
	`justification'.  Renamed `s' to `string'.  Removed `w', `l'.
	Updated all usages.
	(struct outp_class) Removed `magic', `open_global',
	`close_global', `font_sizes', `preopen_driver', `option',
	`postopen_driver', `line_horz', `line_vert', `line_intersection',
	`box', `polyline_begin', `polyline_point', `polyline_end',
	`text_set_font_by_name', `text_set_font_by_position',
	`text_set_font_family', `text_get_font_name',
	`text_get_font_family', `text_set_Size', and `text_get_size'
	members.  Added `open_driver', `close_driver', `line' members.
	Changed interface of `open_page', `close_page', `text_metrics',
	`text_draw' members.  Updated all usages.
	(struct outp_driver) Rearranged members.  Removed `driver_open',
	`res', `horiz', `vert', `horiz_line_spacing', `vert_line_spacing'
	members.
	(struct outp_option_info) Removed.
	(struct outp_driver_class_list) Removed.
	(outp_match_keyword) Changed interface.

	* table.c: (tab_create) Now ignores reallocable argument: tables
	can always be reallocated.  Use pool_create_container().
	Initialize vertical rules to UCHAR_MAX.
	(options_to_font) New function.
	(tab_destroy) Remove futile assignment.
	(tab_realloc) Initialize vertical rules to UCHAR_MAX.
	(text_format) Use xvasprintf() instead of local_alloc().
	(tab_title) Always format the argument, and drop the option
	argument.  Change all callers to agree.
	(tab_natural_width) Adapt to new ->text_metrics() interface.
	(tab_natural_height) Ditto.
	(tab_joint_text) Clear rules within the joined cell.  Now
	necessary because of the default to put spacing between cells.
	(tab_output_text) Use xvasprintf() instead of local_alloc().
	Remove special cases for fixed-width font.
	(rule_to_spacing_type) New function.
	(tabi_driver) Calculate rule widths manually now that we don't
	have ->trh or ->trv.  Implement new default for vertical rules.
	(render_rows) New function.
	(tabi_render) Rewrite in terms of render_rows() for clarity.
	(translate_justification) New function.
	(rule_to_draw_type) New function.
	(get_hrule) New function.
	(get_vrule) New function.
	(render_horz_rule) New function.

	(TAB_FIX) New flag.
	(TAL_3) Removed.
	(TAL_GAP) Added.
	(TAL_SPACING) Removed.
	(struct tab_table) Members `trh', `hrv', `hr_tot', `vr_tot'
	removed.
	[DEBUGGING] (reallocable) Removed.
	(TAT_FIX) Removed.  All references replaced by TAB_FIX.
	(TAT_TITLE) Now implies TAB_EMPH.

	* output.c: (colon_tokenize) Removed.
	(configure_driver_line) Rewrote to use ds_separate().  Fixed leak.

	* html.c, postscript.c, output.c:  Changed to fit the new signature 
	of fn_interp_vars
	
Sun Mar  5 13:19:32 2006  Ben Pfaff  <blp@gnu.org>

	* postscript.c: (postopen) Fix segfault when the active file has
	no title.

Sat Mar  4 13:48:16 2006  Ben Pfaff  <blp@gnu.org>

	We didn't provide a way to define these macros, so obviously
	there's little demand for them.

	* html.c: Don't test for NO_HTML.

	* postscript.c: Don't test for NO_POSTSCRIPT.

	* output.c: Don't test for either of those.

	* Moved files from src directory
