Tue Apr  4 20:13:06 2000  Owen Taylor  <otaylor@redhat.com>

	* pango/pango-context.h: Add user data to PangoContext

	* pango/pangox.[ch] examples/viewer.c: Rework system for create GC's 
	so that	the necessary information is stored on the PangoContext
	instead of being passed to layout_render()

	* pango/utils.[ch] pango/pango-context.c: fribidi-0.1.9
	wants UCS-4 not UCS2; switch accordingly.

	* pango/fonts.c pango/pango-font.h pango/pangox.c: Add functions
	to get overall font metrics, possibly per-language. (Right now,
	just font ascent, descent.) The implementation of this for
	X is horribly complex.
	
Mon Apr  3 20:30:20 2000  Owen Taylor  <otaylor@redhat.com>

	* pango/mapping.c (pango_glyph_string_x_to_index): Fix handling
	of positions at character limits.

	* modules/basic/basic.c (basic_engine_shape): Fix bug that
	was causing mirrored characters not to mirror.

Mon Apr  3 15:16:06 2000  Owen Taylor  <otaylor@redhat.com>

	* pango/glyphstring.c (pango_glyph_string_get_logical_widths):
	Fix off-by-one error for RTL runs.

	* configure.in: Add -lglib to AC_CHECK_LIB(fribidi...)
        (How did this work?) From Matt Wilson.

	* pango/pango-layout.c (pango_layout_check_lines): Correctly deal
	with handling character offsets when breaking lines.

	* modules/arabic/arabic.c (arabic_engine_shape): Fix problem with 
	setting unknown glyph when no arabic-capable font found.

Fri Mar 31 11:29:47 2000  Owen Taylor  <otaylor@redhat.com>

	* pango/pangox.[ch] (pango_x_render_layout[_line]) examples/viewer.c: Add
	capability to render foreground / background colors. The interfaces
	here are possibly certainly not right, or convenient, but
	they should be a start.

Thu Mar 30 17:06:39 2000  Owen Taylor  <otaylor@redhat.com>

	* modules/arabic/*.[ch]: New version of Arabic module
	from Karl Koehler, supporting:

	- More extensive ligatures
	- Some Hamza handling
	- Vowel marks
	- mule-arabic font
	- LangBox font
	- Persian (farsi) (needs testing)

Thu Mar 30 16:49:06 2000  Owen Taylor  <otaylor@redhat.com>

	* modules/basic/basic.c pango/utils.c (find_converter): Use
	"UTF-8" with the dash as the charset name for utf-8. 
	(Change suggested by Adrian Havill <havill@turbolinux.co.jp>)

	* pango/pango-layout.[ch]: Add function to get logical attributes
	of the text string.

Mon Mar 13 11:47:53 2000  Owen Taylor  <otaylor@redhat.com>

	* pango/pango-layout.c pango/pangox.c (pango_x_render_layout): Handle right 
	alignment for width == -1, align within total width of layout.

Mon Mar 13 10:54:48 2000  Owen Taylor  <otaylor@redhat.com>

	* pango/pango-item.[ch]: Memory management functions for PangoItem.

	* pango/*.[ch]: Random constification.
	
	* pango/pangox.c pango/pango-layout.c pango/pango-context.c:
	Add an extra_attrs field to PangoItem. Use this to handle underlining
	for PangoLayout.

	* examples/viewer.c (reload_font): Make paragraphs global
	to save the complexity of passing it around all over the place.

	* pango/pango-layout.[ch] (pango_layout_context_changed): Add
	a function to reset the layout on changes to the layout's
	context.

	* pango/pangox.c (pango_x_make_matching_xlfd): Prefer bitmap
	to scaleable if the discrepancy is < 1 pixel. (Probably not
	the ideal criterion.)

	computation error.

	* pango/pango-layout.c (pango_layout_check_lines): Handle
	text with embedded newlines.

	* pango/pangox.c (pango_x_render_layout): Fix y to refer
	to the top of the layout, not the baseline of the first
	line.

	* pango/pango-layout.c (process_item): Don't wrap if width is
	set to -1.

	* Makefile.am configure.in **/*.[ch]: move libpango/ directory
	and fix all headers to install under include/pango/

Thu Mar  9 19:55:21 2000  Owen Taylor  <otaylor@redhat.com>

	* Release pango-0.8

	* docs/TEXT/coding-style: Added some notes about coding style
	within Pango.

	* modules/*.[ch]: New version from Karl Koehler adding support
	for vowels marks, better ligatures.
	
	* docs/tmpl/*: Doc updates

        * libpango/pango-layout.[ch] libpango/pangox/.[ch]: Add functions
	for handling paragraphs as 2-D objects, not simple lists of lines,
	to make things easier for people using pango-layout.
	 
        * examples/viewer.c: Simplify using the now 2-D layout-capabable
	PangoLayout.
	
	* libpango/fonts.c (pango_font_{get_coverage,find_shaper}): Allow
	NULL language tag.

	* libpango/modules.c (_pango_find_map): Fix for allowing
	NULL language tag.

Wed Mar  8 13:34:57 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pango-layout.[ch]: First draft of highlevel
	driver. It currently only handles a paragraph as a list
	of lines, but it is probably necessary to make it handle
	2D layout for a paragraph as well

	* examples/viewer.c: Move over to new layout driver
	(much of the code moved into pango-layout.c)

	* libpango/glyphs.c libpango/pango-glyphs.h: Fixes to get_extents(),
	add pango_glyph_string_get_logical_widths.

	* libpango/pango-itemize.c: Handle 0-length text properly.

	* libpango/pangox.c: When loading particular sized fonts,
	use the original XLFD, since XFree86 doesn't handle wildcards
	in aliases properly.

	* libpango/pangox.[ch] (pango_x_render_layout_line): Add function
	to render an entire PangoLayoutLine.

	* libpango/reorder-items.c: Add a note to the effect
	that pango_reorder_items() is basically replaced by a
	similar function in PangoLayout.

Wed Mar  8 10:58:56 2000  Owen Taylor  <otaylor@redhat.com>

	* modules/arabic/arconv.c (shapecount): Fix from Karl
	Koehler to joining behavior.

	* modules/Makefile.am modules/arabic/*: Added arabic
	shaper from Karl Koehler <koehler@or.uni-bonn.de>

	* modules/basic/tables-{small,big}.i: Remove arabic
	from the ranges that the basic shaper marks as "exact".

	* examples/HELLO.utf8: Partially alphabetize, add arabic.

Mon Mar  6 21:03:28 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pango-layout.[ch]: Started work on highlevel layout driver.

Mon Mar  6 20:55:32 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/mapping.c example/viewer.c: 
	* modules/hangul/hangul.c modules/basic/basic.c modules/tamil/tamil.c:
	
	Convert log_clusters[] use from char offsets to byte offset - should
	make it easier to have all interface deal with stuff in byte offsets.

	* libpango/mapping.c libpango/pango-glyph.h: Rename x_to_cp and cp_to_x
	to make them "member functions" of glyph_string.
	
	* libpango/pango-types.h: Add a rectangle type for use in storing
	glyph/glyph-string extents, plus macros for extracting ascent/descent.
	
	* libpango/fonts.c libpango/pango-font.h libpango/pangox.c: Virtualize
	glyph extents function into the font.

	* libpango/pangox.c modules/*/*.c examples/viewer.c: Convert over to
	new rationalized unit system - everything in 1000ths of a point
	or 1000ths of a glyph unit.

	* libpango/pango-glyph.h libpango/glyphstring.c: Add function to get
	extents of a glyph string. (We may want to fastpath the width in
	the future, since getting the width seems to be a very common 
	and time-critical operation)

Mon Feb 28 19:46:35 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/fonts.c libpango/pango-fonts.h: Add functions
	to convert font descriptions to and from human-readable
	strings.

	* examples/viewer.c: Use functions from libpango instead
	of rolling our own font-description conversion functions.

Fri Feb 25 15:04:21 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/{fonts.c,pango-font.h,pango-context.[ch],pangox.c,
	pango-attributes.c,examples/viewer.c: Add size to the 
	font description structure instead of continually passing
	it around as an extra argument.

	* libpango/pangox.c: Take screen resolution into account when
	choosing fonts, instead of assumming point == pixel.

Fri Feb 25 12:32:01 2000  Owen Taylor  <otaylor@redhat.com>

	* configure.in examples/Makefile.am: If GTK+ test fails,
	just skip the example program.

	* pango-config.in pango.spec.in: Add a simple pango-config
	script to the build. (pango-config --libs pangox really
	should add the X libraries, but we'll omit that for the
	moment.)

Sat Feb 19 18:51:35 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pangox.c (pango_x_make_matching_xlfd): Fix problem
	  where charsets specified in alias files where being ignored
	  and treated as wildcards.

Sat Feb 19 17:46:49 2000  Owen Taylor  <otaylor@redhat.com>

	* README: Fix Dov's name.

	* configure.in: Release 0.7

	* examples/Makefile.am (aliasdir): Install example
	  pangox_aliases file.

	* examples/Makefile.am (bin_PROGRAMS): Install 
	  pango-viewer.

	* docs/tmpl/*: Updated templates.

Wed Feb 16 16:39:46 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pango-coverage.c (pango_coverage_get): Make refcounted.

	* libpango/modules.c (struct _PangoEnginePair): Since we don't
	  currently unload engines, cache loaded engines. (Not really
	  quite satisfactory, but should work OK)

	* libpango/pango-context.c (pango_context_get_font_description):
	  Added a global font description.

	* libpango/modules.c (_pango_find_map): Allow NULL
	  language tags.

        * libpango/Makefile.am: make dist fixups.
	
        * Makefile.am pango.spec.in: Add a spec file
	
	* examples/HELLO.utf8: Change Maltese to a different
	  phrase to include some unique Maltese characters.
	  (Suggestion from Steven R. Loomis)

	* libpango/Makefile.am modules/Makefile.am libpango/modules.c:

	* docs/**: Added recent API changes.
	* libpango/pango-context.c: Doc comment fixes

	* configure.in: Add in directories from unicode-config
	when running AC_CHECK_LIB on libunicode.

Thu Feb 10 23:45:27 2000  Owen Taylor  <otaylor@redhat.com>

	* configure.in: Up version to match 0.6 release that
	was made yesterday.

	* examples/viewer.c (main): Look for fixed if sans
	isn't found as an initial font.

	* modules/Makefile.am: Add an install rule to
	run pango-querymodules.

	* modules/*/Makefile.am (module_LTLIBRARIES): Set up
	appropriate install rules.

	* libpango/Makefile.am: Break the X code out into a
	separate library.

Thu Feb 10 20:19:39 2000  Owen Taylor  <otaylor@redhat.com>

	* examples/viewer.c: Fix some runtime and compile-time warnings.

	* modules/hangul/hangul.c (hangul_engine_shape): Shape the
	  string with the unknown glyph rather than giving a warning
	  when the font doesn't have any of the necesary charsets.

Thu Feb 10 19:57:27 2000  Owen Taylor  <otaylor@redhat.com>

	* examples/viewer.c: Add style selector, rewrite family
	  selector to use list_families().

	* libpango/pango-context.[ch] libpango/pango-font.h libpango/pangox.c
	  libpango/fonts.c: Add calls to list families, modify list_fonts()
	  call to take an optional "family" parameter for the purpose of
	  listing the fonts within a family. 

Wed Feb  9 14:04:35 2000  Owen Taylor  <otaylor@redhat.com>

	* TODO: updates.

	* docs/*: Added some docs on font handling, both general
	and for X.

Tue Feb  8 15:05:17 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pangox.c: Moved the primary size and charset matching
	inside of Pango instead of on the font server. This allows us
	to do better matching, and only scale scaleable fonts, and not
	scale bitmaps. Also, match size and charset simultaneously,
	so that we can handle the cases where all sizes are not available
	in all charsets better.

Mon Feb  7 20:27:35 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pangox.c (pango_x_names_for_size): Start at reworking

	* examples/viewer.c (make_families_menu): Switch the option
	menu for a combo box.

	* examples/pangox_aliases: Add a demo alias file.

	* libpango/pangox.c: Add a font-alias mechanism allowing.

	* examples/viewer.c (make_font_selector): Added a spin-button for
	size.

Wed Feb  2 20:49:21 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pangox.c (pango_x_get_unknown_glyph): Add a call to get
	a glyph for unknown an unknown char.

	* modules/basic/basic.c: use pango_x_get_unknown_glyph.

	* libpango/utils.[ch] (_pango_guchar4_to_utf8): Added util function
	for coverting wide chars to utf8.

	* libpango/pangox.c (pango_x_font_get_coverage pango_x_font_get_shaper):
	Initial implementations.

        * libpango/pango-types.h: Conditionally define G_N_ELEMENTS() when
	using glib-1.3.
	
	* modules/basic/basic.c modules/hangul/hangul.c modules/tamil/tamil.c:

        * libpango/pango-engine.h: Added a get_coverage() function
	to the PangoEngineShape vtable.
	 
	* modules/basic/basic.c modules/hangul/hangul.c modules/tamil/tamil.c:
	Added get_coverage() functions. The basic.c one is incredibly 
	inefficient (but caching may make that matter that much).
	The Hangul one needs checking.

Wed Feb  2 00:07:13 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pango-*.h: The great header file reorganization.
	Split up roughtly by objects.

	* libpango/pango-font.h libpango/fonts.h: Add generic
	font-loading and listing interfaces.

	* libpango/pangox.c: Implement font-listing/loading interfaces
	for X.

	* libpango/pango-context.[ch]: Flesh out context structure.
	Add appropriate accesors, font loading-methods, etc.

	* libpango/pango-coverage.[ch]: Coverage map objects.

	* examples/viewer.c: First stab at adding font-selection. Majorly
	deficient for the moment until we add font lists and fallbacks
	based on coverage maps.

Thu Jan 27 16:50:51 2000  Owen Taylor  <otaylor@redhat.com>

	* docs/**: Updates to match recent API changes.

Mon Jan 17 22:03:24 2000  Owen Taylor  <otaylor@redhat.com>

	* modules/hangul/hangul.c modules/tamil/tamil.c:
	  Updated to use new X font mechanism.

	* libpango/pangox.[ch]: Misc bugfixes, no longer segfaults.

Mon Jan 17 18:29:39 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pangox.[ch] modules/basic/basic.c: back away from
	  the strict charset model to having subfonts arbitrarily indexed. The
	  charset-index model didn't allow proper fallbacks.

	  Add a function pango_x_list_subfonts() function that lists
	  subfonts in the proper order for a given list of charsets.

	  (segfaults currently, will fix pronto)

Sat Jan 15 03:17:35 2000  Owen Taylor  <otaylor@redhat.com>

	* pango/glyphstring.c pango/mapping.c pango/pangox.c
	  modules/basic.c examples/viewer.c:

	  Switch GlyphStrings to have a single array of
	  PangoGlyphInfo instead of multiple arrays. Rename
	  PangoGlyphIndex to PangoGlyph.

Sat Jan 15 01:06:45 2000  Owen Taylor  <otaylor@redhat.com>

	* libpango/pangox.c libpango/pangox.h libpango/fonts.c
	  libpango/glyphstring.c modules/basic/basic.c:

	  Eliminate PangoCFont; For X, encode charset into upper
	  16 bits of 32 bit glyph IDs. Revise X core <=> module
	  interfaces to support this change.

	  Remove support for X_XLFD_FONT_RANGES, which has been
	  disavowed by its proponents, in favor of checking metrics
	  to figure out if the relevant characters are there.

	  Rework operation of basic module to be faster and simple.

	* modules/Makefile.am: temporarily comment out Tamil and
	  Hangul modules until I finish mucking with the
	  X font interfaces.

Fri Jan 14 12:08:43 2000  Owen Taylor  <otaylor@redhat.com>

	* examples/HELLO.utf8: Add Pango properly spelled.

	* modules/basic/{basic.c,tables-{big,small}.i}:
	 Rewrote basic module to support subset fonts meaningfully.
	 This meant revising the algorithm used to look
	 up a font for each character independently.
	 Which required aggresive caching here and in the
	 font code to give half-way decent performance.

	 Added support for ISO-10646-1 fonts.

	* libgscript/fonts.c (g_script_font_[get/set]_data): Add the
	  ability to add user data to a font.

	  sets for a font.
	- Loading a component font with a particular XLFD.
	- Finding the range of present characters for a given XLFD.

   	  Also added tons of caching.

	identify it as a test of the above.

	* gscript/gscript.h gscript/gglyphstring.c modules/basic/basic.c:
	Add another field into the GGlyphString which holds
	a mapping from glyphs to logical clusters.

	* libgscript/gscript.h (struct _GScriptLangRange):
	Make it start-length like everything else, not
	start-end.

	* modules/basic/basic.c: Added ability to use
	multibyte character sets. (Right now, they have
	to be converted by iconv into EUC encoding, but
	that can easily be extended).

	Added simply CJK support. This really bloats and
	slows down the module because the range-based
	encoding we use to map characters onto character-sets
	wasn't designed for CJK-style charsets. But it's
	better than nothing for now.
	
	* libgscript/reorder-items.c (reorder_items_recurse): Fix
	bug with variable initialization.

	* examples/viewer.c (draw): Compute line increments.

	* libgscript/gscriptx.c (g_script_x_[glyph]_extents): Added
	logical_ascent/descent parameters.

	* examples/viewer.c: Commented

	* configure.in Makefile.am: automake'd and libtoolized.
