    	* gtk/gtkwidget.c: Remove all references to
    	offscreen flag which was no longer used.
    	* gtk/gtkprivate.h (enum): Remove unused flags and compress.
    	* gtk/gtkframe.c (gtk_frame_set_label_widget): Check
    	for non-null label_widget->parent.
    	* gtk/gtkentry.c: Get rid of code to deal with PangoAttribute
    	which no longer was used.
    	* gdk/gdkpango.c (gdk_pango_context_get_info): make static.
    	* gdk/gdkpango.c (gdk_draw_layout[_line]): Add checks
    	for null arguments.
    	* gdk/x11/gdkgeometry-x11.c (gdk_window_scroll): add
    	check for destroyed windows.
    Thu Jun  1 13:48:45 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkimmulticontext.c: Add a finalize method and unref
    	the slave context there.
    	* gtk/gtkinvisible.[ch]: Make reference counting behavior
    	identical to GtkWindow.
    Thu Jun  1 01:54:11 2000  Owen Taylor  <otaylor@redhat.com>
    	* Makefile.am gdk/gdkpango.c: Copy the layout render function from
    	pangox to here, so we can write them independent of rendering
    	system, using GDK primitives.
    	* gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c
    	gdk/x11/gdkdrawable-x11.c: Remove draw_layout() from the vtable,
    	since we have a rendering-system independent implementation in
    	terms of draw_glyphs().
    	* gdk/gdkpango.c gdkdrawable.h (gdk_draw_layout_line): New
    	function to render a single line.
    	* gdk/x11/gdkpango.c: Move the guts of this file mostly
    	into ../gdkpango.c, which simplifies things, since we
    	don't have to deal with raw X gc's.
    Fri May 19 04:28:16 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextlayout.[ch]: Add get_log_attrs() function to
    	get the logical attributes for a given GtkTextLine.
    Tue May 30 16:05:39 2000  Owen Taylor  <otaylor@redhat.com>
    	* gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Track
    	g_locale_get_codeset() to g_get_codeset() change.
    Tue May 30 15:03:19 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/testcalendar.c (calendar_font_selection_ok): Use font
    	* gtk/gtkentry.c (gtk_entry_draw_text): Center text within
    	the entry.
    	* gtk/gtkfontsel.c (gtk_font_selection_dialog_init): Start of
    	redoing (vastly simplifying) for Pango. Still needs quite
    	a bit of work. (Size selection is currently poor. List of
    	predefined sizes is not a good idea, since all of these
    	sizes won't necessarily be distinct.)
    Tue May 30 13:50:19 2000  Owen Taylor  <otaylor@redhat.com>
    	* gdk/x11/gdkfont-x11.c (gdk_font_charset_for_locale): Handle
    	CODESET results for LANG=C.
    Mon May 29 15:49:10 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkrc.[ch]: Add a 'font_name' declaration to RC
    	which takes a stringized pango font description;
    	ignore the older 'font' and 'fontset' declarations.
    	* gtk/gtkstyle.c gtk/gtkrc.c: Fill in the style->font
    	field with a GdkFont derived via gdk_font_from_description(),
    	for compatibility. (Should we just remove it entirely?
    	Probably too much compatibility breakage, but people
    	should be migrating to the new Pango stuff as quickly
    	as possible.)
    Mon May 29 15:47:41 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkentry.c gtk/gtkclist.c: s/pango_font_unref/g_object_unref/.
    Mon May 29 15:44:46 2000  Owen Taylor  <otaylor@redhat.com>
            * gtk/gtkcalender.c: Roughly pango-ized. Really needs
    	redoing; there are some bugs in size allocation right
    	now, the semi-existant distinction between header / day
    	fonts was removed, but, with Pango, could actually
    	be made functional in a nice way.
    	* gtk/testcalender: Move calender from examples into this
    	directory as a test program. (We really need to restrcture
    	testgtk into a whole directory full of tests for every
    	widget or functionality group, separated into multiple .c
    Mon May 29 15:19:56 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/testgtk.c (file_exists): Fix stupid typo that
    	was keeping RC file from being loaded.
    	* gtk/testgtkrc gtk/testgtkrc2: Test new pango-ized
    	RC file font code.
    Mon May 29 14:31:27 2000  Owen Taylor  <otaylor@redhat.com>
    	* gdk/gdkfont.h gdk/x11/gdkfont-x11.c (gdk_font_from_description):
    	Add function to load a GdkFont from a PangoFontDescription.
    Fri May 26 17:16:40 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/frame.[ch] gtkaspectframe.c: Make frame widgets able
    	to have any widget for the label, use a GtkLabel widget
    	to display the text. (Based partially on a patch from
    	Anders Carlson.)
    	(Quite a bit of code reorganization - strip 90% of the
    	guts out of gtkaspectframe and add a single virtual
    	func to GtkFrameClass - compute_child_allocation.)
    Fri May 26 12:00:02 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkctree.c gtk/gtkclist.[ch]: Pangoized.
    	(Removed clist->row_center_offset field because caching
    	it wasn't saving time or code, added private function
    Wed May 24 15:59:37 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkaccellabel.c: Pangoized.
    	* gtk/[hv]ruler.c: Pangoized
    Mon May 22 19:23:59 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkfilesel.c (gtk_file_selection_init):
    	Use gtk_clist_set_column_auto_resize() to remove need
    	need for manual column width computations.
    Mon May 22 18:50:26 2000  Owen Taylor  <otaylor@redhat.com>
            * gtk/gtktooltips.[ch]: Replace custom drawing with a GtkLabel,
    	ensuring Pango correctness, and considerably simplifying the
    	* gtk/gtklabel.c gtk[hv]scale.c: 1000 => PANGO_SCALE.
    	* gtk/gtklabel.c (gtk_label_size_request): Fixed incorrect
    	getting of numbers of lines.
    	* gtk/gtklabel.c (gtk_label_size_request): Set the requisition
    	to the actual requested width of the lable, not to the wrap
    	width we set.
    	* gtk/gtktextchild.h: Remove extraneous include of gtk/gtk.h.
    	* gtk/gtktextbtree.c gtk/gtktextbuffer.c gtk/gtktextlayout.c
    	  gtk/gtktextview.c gtk/gtktextview.[ch]: Fix up includes.
    	* gtk/gtktextview.c: Fix structure inheritance.
    	* gtk/gtkprogressbar.c: Pangoize.
    Mon May 22 15:47:30 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextview.c (gtk_text_view_get_first_para_iter): Encapsulate
    	in a function.
    	* gtk/gtktextlayout.c (find_display_line_above): Fixed
    	bug with computing line tops.
    	* gtk/gtktextview.c (changed_handler): Fix < , <= confusion.
    Thu May 18 18:53:31 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextdisplay.c (gtk_text_layout_draw): Fix up the x_offset
    	and y_offset coordinates to do what we need now. (The offset between
    	buffer and layout coordinates has been reintroduced, but is a
    	bit different than before.)
    	* gtk/gtktextview.[ch]: No longer inherit from GtkLayout; instead
    	handle the adjustments ourselves, and scroll as necessary using
    	the new gdk_window_scroll().
    	The advantage of this is that when we are incrementally revalidating,
    	we are essentially rearranging things around the visible portion
    	of the screen. With the old setup, the visible portion of the
    	screen was moved around in the layout, so scrolling and redrawing
    	to track that caused jumping of the display. Since we now
    	control the scrolling ourselves, we can suppress this and
    	only redraw when things actually change.
    Thu May 18 18:47:25 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextbtree.c (redisplay_mark): We need to invalidate
    	the region not just redisplay it after-all, since we store the
    	cursors in the LineDisplay. (Ugly interactions here between
    	GtkLayout and GtkTextBTree here.)
    	* gtk/gtktextbtree.c (redisplay_region): Fixed reversed comparison.
    Thu May 18 18:43:21 2000  Owen Taylor  <otaylor@redhat.com>
    	* gdk/gdkwindow.h gdk/x11/gdkgeometry-x11.c (gdk_window_scroll):
    	Added function to scroll contents of a window while keeping the
    	window constant. Works by XCopyArea or guffaw-scrolling depending
    	on the details of how the window is set up. (guffaw-scrolling
    	still needs to be filled in.)
    Wed May 17 22:36:53 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextiter.c gtk/gtkmain.c: Add a debug key for the text widget,
    	move the debugging that was tied to a global variable
    	to that.
    	* gtk/gtkmarshal.list: Add NONE:INT,INT,INT
    	* gtk/gtktextbtree.[ch] gtk/gtktextlayout.c: Keep a separate
    	validated flag, in line data instead of setting height/width to
    	-1. This allows us to perform operations with partially invalid
    	buffer (using the old size for invalid lines) and thus to do
    	incremental vaidation. Keep height/width aggregates up to date
    	when deleting text and rebalancing the tree.
    	* gtk/gtktextbtree.[ch]: Add functions validate a line
    	(gtk_text_btree_validate_line), and to validate up
    	to a number of pixels (gtk_text_btree_validate).
    	* gtk/gtktextlayout.[ch]: Add an ::invalidated signal
    	that indicates that something is changed and a revalidation
    	pass is needed. Change ::need_repaint to ::changed, and
    	make it take old and new yranges instead of a rectangle.
    	* gtk/gtktextbtree.[ch] gtk/gtktextlayout.[ch]: Move
    	the line_data_destroy() function from
    	gtk_text_btree_add_view() to a virtual function in
    	* gtk/gtktextbtree.[ch]: Remove gtk_text_btree_get_damage_range(),
    	since we are handling partial repaints in a different fashion
    	* gtk/gtktextbtree.[ch]: Only repaint the changed portion
    	of the selection instead of queueing a repaint on the
    	entire widget.
    	* gtk/gtktextbuffer.[ch] gtk/gtktextbtree.[ch]: Move
    	get_selection_bounds() down to btree, make the function
    	in buffer a wrapper around the btree function.
    	* gtk/gtktextlayout.[ch]: Add functions to check if the
    	layout is valid and to recompute either a range of pixels
    	aroudn a line or a certain total number of pixels.
    	* gtk/gtktextlayout.[ch]: Cache a single line display;
    	now that we only redraw the needed portions, the hit rate
    	for this cache is quite high.
    	* gtk/gtktextview.[ch]: Keep track of the first paragraph
    	on the screen so that when re-laying-out the buffer, we can
    	keep the same place. This requires connecting to ::value_changed
    	on the adjustments
    	* gtk/gtktextview.[ch]: Add idle functions to revalidate
    	the buffer after we receive an ::invalidated signal.
    Wed May 17 22:10:47 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtklayout.c (gtk_layout_size_allocate): Set upper
    	to max of allocation and layout size, not just to the
    	layout size.
    	* gtk/gtk[hv]scrollbar.c (gtk_[hv]scrollbar_calc_slider_size):
    	Invalidate window so it gets redrawn properly.
    	* gdk/gdkwindow.c (gdk_window_invalidate_rect): Allow rect == NULL
    	to mean the entire window.
    	* gdk/gdkevents.h: Move definition for GDK_PRIORITY_REDRAW
    	into public header.
    Mon May 15 14:51:31 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextmark.c (gtk_text_mark_get_name): Add function
    	to get the name of a mark.
    	* gtk/gtktextlayout.c (gtk_text_layout_get_line_at_y): Add a function
    	to find the paragraph from a y position.
    Thu May 11 12:57:20 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextbtree.c (gtk_text_btree_node_invalidate_upward): Valid
    	nodes have width/height >= 0, not > 0.
    Tue May  9 21:29:06 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c (gtk_text_layout_get_line_display):
    	Add a size_only flag, so when we only need the size, we don't create
    	useless appearance attributes.
    	* gtk/gtktextview.c (gtk_text_view_ensure_layout): Remove
    	duplicate setting of font description.
    	* gtk/gtkscale.c: Use PANGO_SCALE instead of 1000
    Wed Apr 26 01:53:23 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/Makefile.am (EXTRA_DIST): Add OLD_STAMP into
    	EXTRA_DIST. It does not work well when the file that
    	everything depends on is not in the tarball.
    Wed Apr 26 00:56:14 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/testgtk.c: Some hacks and fixes so that it basically
    	works when not sitting in the GTK+ build tree.
    2000-05-03  Havoc Pennington  <hp@redhat.com>
    	* gtk/gtktextbtree.c (gtk_text_line_next_could_contain_tag):
    	Properly determine the ordering of the tag root and the current
    	line within the tree. Previous algorithm only worked if the tag
    	root's immediate parent was the common root of both the current
    	line and the tag root.
    Wed Apr 26 00:43:00 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextlayout.c (set_para_values): Fix some bugs in
    	* gtk/gtktextview.c (gtk_text_view_ensure_layout): Track
    	the widget text directional dynamically.
    	* gtk/gtktextview.[ch]: Added functions to get and set default
    	wrap mode.
    Tue Apr 25 23:47:38 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextlayout.c (gtk_text_layout_get_iter_location): Fix bug
    	in cursor location computation.
    Tue Apr 25 23:22:59 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtklayout.c (gtk_layout_set_size): Clamp hadjustment/
    	vadjusment values properly when layout gets smaller.
    	* gtk/gtktextview.c (need_repaint_handler): Areas being
    	passed in are far completely inaccurate, and sometimes
    	too small, so, for now, just queue a redraw on the
    	whole visible region.
    2000-04-25  Havoc Pennington  <hp@redhat.com>
    	* gtk/gtktextbtree.c (summary_destroy): new function to
    	destroy tag summary nodes
    	(gtk_text_line_next_could_contain_tag): this function was
    	totally broken if the line passed in wasn't below the tag
    	root. Fix it.
    	(gtk_text_btree_first_could_contain_tag): In the tag == NULL
    	"wildcard" case, we have to do a linear scan. Blah.
    	(gtk_text_btree_last_could_contain_tag): In tag == NULL case,
    	we have to do the linear scan
    	(tag_removed_cb): When a tag is removed from the tag table,
    	remove the GtkTextTagInfo node from the btree.
    	(gtk_text_btree_spew): Implement the spew function, for
    	our debugging pleasure.
    Tue Apr 25 19:40:18 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextlayout.c (gtk_text_layout_set_buffer): Fix
    	a problem with referring to the wrong buffer.
    	* gtk/gtkentry.c: Fix focus-in/focus-out confusion.
    	* gtk/gtkrc.c gtk/gtkstyle.c: Moving setting default
    	font description to gtk_style_new() - otherwise things
    	don't work without a .gtkrc file.
    	* gtk/gtktextbuffer.c (gtk_text_buffer_new): Sink the
    	tags table if we create it ourself, too.
    	* gdk/gdktypes.h (enum): Move GDK_RELEASE_MASK, since
    	it was conflicting with XKB modifiers.
    	* gtk/gtktextview.[ch]: Add simple support for
    Mon Apr 24 19:34:18 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkentry.c (gtk_entry_move_cursor_visually): Fix problem
    	with deletion from last commit.
    Mon Apr 24 19:29:40 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkwidget.c (gtk_widget_create_pango_context): Set the language
    	in the context from the current locale.
    	* gtk/gtkentry.c (gtk_entry_size_request): Use language from the
    	context, not hardcoded value.
    	* gtk/gtkentry.c (gtk_entry_move_cursor): Make character movement visual,
    	not logical.
    Sun Apr 23 23:39:18 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkentry.c gtk/gtktextdisplay.c: Don't handle selections as
    	attributes - that doesn't handle partial-glyph selection
    	properly. Instead use new pango_layout_line_get_x_ranges()
    	functionality to draw the selection.
    	* gtk/gtkentry.c: Simplify code since pango_layout_line_index_to_x()
    	now properly handles out-of-range coordinates.
    	* gtk/gtktextbuffer.c: Emit "mark_set" when the cursor is moved.
    	* gtk/gtktextiter.h gtk/gtktextiterprivate.h: Make gtk_text_iter_get_line_byte()
    	* gtk/gtktextlayout.[ch]: Properly set the direction in the PangoContext
    	for paragraphs opposite to the base direction of the widget.
    	* gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Fixes for alignment.
    	* gtk/gtktextlayout.c: Don't split segments on marks, since that
    	causes Arabic words to reshape as you cursor through.
    	* gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Implement virtual
    	cursor position when moving vertically with the arrow keys and
    	scrolling with page-up/page-down. (Arrow keys save only the X,
    	scrolling saves both X and Y.)
    	This means you can line-up / line-down or page-up / page-down
    	without losing your place, and also that moving vertically
    	with the cursor keys keeps the same X position, not the same
    	character count:
    	* gtk/gtktextlayout.[ch] gtk/gtktextview.[ch]: Make vertical
    	arrow keys move by display lines, not paragraphs.
    Tue Apr 18 14:16:50 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtklayout.c: Make sure that the bin window is at least
    	as big as the allocation. (Should we also make sure that the
    	bin window is big enough to completely cover widget->window?)
    	* gtk/gtktextview.c (gtk_text_view_get_visible_rect): Add
    	function to get the onscreen rectangle.
    	* gdk/x11/gdkwindow-x11.c (gdk_window_get_pointer): Correctly account
    	for offsets in window coordinates.
    Sun Apr 16 16:13:27 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkentry.c (gtk_entry_get_cursor_locations): Fix index/offset
    	* gtk/gtktextview.c (gtk_text_view_ensure_layout): Set the default direction
    	from the widget direction.
    	* gtk/gtktexttag.c gtk/gtktexttagprivate.h (gtk_text_tag_set_arg):
    	Add a "direction" attribute.
    	* gtk/gtktextview.c: global s/tkxt/text_view/.
    	* gtk/testtext.c: Added long block of text in Arabic, to test out
    	the direction attributes. (Some problems with the shaping system
    	for arabic become obvious - like the fact the cursor splits words
    	into unjoined pieces.)
    Fri Apr 14 12:54:34 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktextdisplay.c (render_layout): Add overstrike handling.
    	* gtk/gtktextlayout.c: Fix up alignment.
    	* gtk/testtext.c: Add some tests for centering, wrapping.
    Fri Apr 14 09:26:22 2000  Owen Taylor  <otaylor@redhat.com>
    	* gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkwindow.c gdk/x11/gdkdrawable-x11.c:
    	Add a draw_glyphs() operation to the drawable vtable and gdk_draw_glyphs().
    	If we wrote GTK+-specific layout-render function this could just replace
    	the draw_layout() operation in the vtable.
    	* gtk/gtkentry.c: Move guts of gtk_entry_get_cursor_locations to
    	pango_layout_get_cursor_pos() and use that function.
    	* gtk/gtktextchild.[ch]: add gtk_ onto pixmap_segment_new(), since it
    	is a non-static symbol.
    	* gtk/gtktextbtree.[ch]: Replace gtk_text_btree_find_line_data_by_y()
    	with gtk_text_btree_find_line_by_y()
    	* gtk/gtktextdisplay.c: Rewrote for Pango - uses a custom layout
    	renderer that handles GtkTextAppearance attributes.
    	* gtk/gtktexttag.[ch] gtk/gtktexttagprivate.h:
    	  - Move the values in the style that don't affect geometry into a
    	    GtkTextAppearance structure.
    	  - Change underline to take a PangoUnderline and "font" a string
    	    representation of a font description
    	  - Add a "font_desc" attribute which takes a FontDescription structure.
    	* gtk/gtktextlayout.[ch]:
    	  - Get rid of the display-line list per each line. Instead, we
    	    generate, on demand, a GtkTextLineDisplay structure which]
    	    contains a PangoLayout * and other necesary information
    	    (offsets, cursor locations) for displaying a paragraph.
    	  - Get rid of the code to wrap lines, create display chunks,
    	    etc. Instead, we just go through a paragraph and convert
    	    it into the necessary inputs to a PangoLayout.
    	  - Implement a new attribute type, GtkTextAttrAppearance. This
    	    holds a GtkTextAppearance, and is used to pass colors,
    	    stipple, etc, through from the layout to the display without
    	    having to use lots and lots of individual attributes.
    	  - Reimplement gtk_layout_get_iter_at_pixel() gtk_layout_get_iter_pos()
    	    in terms of PangoLayout functions.
    	* gtk/gtktextview.c:
    	  - Handle passing the necessary PangoContext to the layout
    	  - Some fixups in painting to deal with the automatic backing store
    	    and offsetting of GTK+-1.4
    	  - Add a style_set handler so that the default style reacts
    	    properly to theme changes.
    	* gtk/gtktext?*.[ch]: Random code-style fixes.
    	* gtk/testtext.c: Substitute in languages that Pango handles now for Thai
    Mon Apr 10 10:33:45 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktext?*.[ch]: Check in Havoc's port of the Tk text widget,
    	in original form preparatory to Pango-ization and gdkimcontext-ization.
    Thu Apr  6 19:25:39 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkimcontext.c: Move default implementations to real_* vfuncs,
    	so that we can derive from gtkimcontext in language bindings properly.
    Thu Apr  6 16:02:52 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkimcontextsimple.[ch]: Use gdk_keyval_to_unicode to gdk_unicode_to_keyval.
    	Add a compose table including (almost) all the compose combinations
    	from X. This is 6k of static, shared data as opposed to 50k or so of dynamic
    	data in the XIM implementation.
    	* gdk/gdk.h gdk/gdkkeyuni.c gdk/win32/gdkevents-win32.c (gdk_keyval_to_unicode, gdk_unicode_to_keyval):
    	Moved functions to convert keyvalues from and to unicode here from
    	the win32 port and made them public.
    Wed Apr  5 16:37:29 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkeditable.c (gtk_editable_insert_text): Allow new_text_length == -1.
    Wed Apr  5 16:27:45 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtkimcontext.[ch]: Base class for new input context system
    	* gtk/gtkimmulticontext.[ch]: Proxy input context that allows
    	the real input context implementation to be loaded from modules
    	and switched on the fly.
    	* gtk/gtkcontextsimple.[ch]: Simple implementation of an input
    	context that just does direct keysymbol => unicode translation.
    	* gtk/gtkentry.[ch]: Start switching editing over to using
    	GtkInputContext. (No handling of preedit yet.)
    Wed Apr  5 15:48:41 2000  Owen Taylor  <otaylor@redhat.com>
    	* gtk/gtktypeutils.h (GTK_CHECK_GET_CLASS): Fix problem with one too
    	many substitutions. (klass should not be subsituted.)
    Wed Apr  5 00:18:14 2000  Owen Taylor  <otaylor@redhat.com>
    	* configure.in: Add checks for Pango
    	* configure.in docs/Makefile.am: Add test for sgml2html
    	and allow 'make dist' without building html, but print out
    	warnings in that case. (For making snapshots)
    	* gdk/Makefile.am gdk/x11/Makefile.am gtk/Makefile.am:
    	Add Pango libraries and C flags
    	* gdk/gdkdraw.c gdk/gdkdrawable.h gdkwindow.c gdk/x11/gdkdrawable-x11.c:
    	Add function (gdk_draw_layout) to draw a pango layout.
    	* gdk/gdkpango.h gdk/x11/gdkpango-x11.c: New file with functions
    	for getting Pango contexts for GDK.
    	* gtk/gtkeditable.c: Get rid of dead code gtk_editable_parent_set()
    	* gtk/gtkentry.[ch]: Complete rewrite to use Pango, add bidirectional
    	* gtk/gtkentry.c: Hack in simple Hebrew input with direct
    	keysym => unicode translations. More languages can be added
    	here, but real input-method support is needed.
    	* docs/Changes-1.4.txt: Added note about entry behavior.
    	* gtk/gtkenums.h gtk/gtkwidget.[ch] testgtk.c gtkprivate.h: Add functions
    	to set the reading direction for a widget and the global direction.
    	Add test which allows toggling the global direction. Two private
    	flags are used to store the direction. (GTK_DIRECTION_SET + GTK_DIRECTION_LTR)
    	* gtk/gtkcheckbutton.c gtk/gtkframe.c gtk/gtkhbbox.c gtk/gtkhbox.c
    	  gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktable.c
    	* gtk/gtk[hv]scale.c gtk/gtkscale.[ch]: Draw numbers using Pango
    	* gtk/gtklabel.[ch]: Moved to Pango and considerably rewritten. Line breaking,
    	underlining now handled by Pango.
    	* gtk/gtkstyle.[ch] gtk/gtkrc.[ch]: Add a PangoFontDescription
    	to RCStyle and Style. (Having both this and the old font name and GdkFont
    	is temporary.)
    	* gtk/gtkwidget.[ch] (gtk_widget_create_pango_{context,layout}): Added
    	convenience functions for creating contexts and layouts for widgets.
    	* gtk/testgtk.c: Enhance label tests with multilingual labels.
