Havoc Pennington 7a4c689387 Some updates
2000-10-18  Havoc Pennington  <hp@redhat.com>

	* gtk/gtk-sections.txt: Some updates

	* gdk/gdk-sections.txt: remove GdkPixbufAlphaMode

	* gdk-pixbuf/gdk-pixbuf-sections.txt: Add new API, remove
	GdkPixbufClass/GdkAnimationClass since those are private

	* gdk-pixbuf/Makefile.am (IGNORE_HFILES): ignore more headers

2000-10-18  Havoc Pennington  <hp@redhat.com>

	* gtk/gtktextiter.c (gtk_text_iter_forward_to_newline): Fix a bug
	where any number of empty lines would get skipped

	* gtk/gtktextiter.h: Remove padding from GtkTextIter; live on the
	edge.

	* gtk/gtktextiter.c (gtk_text_iter_make_surreal): enhance the
	warning about invalid iterators (explain more thoroughly)
	(gtk_text_iter_in_region): rename gtk_text_iter_in_range

	* gtk/gtktextview.c (FOCUS_EDGE_WIDTH): Make focus rectangle less
	big

	* demos/*.c: Add error handling

	* gtk/gtktextbuffer.c: don't modify const iterators

	* gtk/gdk-pixbuf-loader.c: Add full error handling here

	* gtk/gtkimage.c (gtk_image_set_from_file): ignore errors
	on file load

	* gtk/gtkiconfactory.c: Update to reflect addition of error
	handling to gdk-pixbuf loaders

2000-10-16  Havoc Pennington  <hp@redhat.com>

	* gdk-pixbuf-io.c (gdk_pixbuf_get_module)
	(gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
	add error reporting here also

	* make-inline-pixbuf.c (main): use GError

	* io-xpm.c: include unistd.h

	* gdk-pixbuf-util.c: include string.h

	* io-*.c: add error reporting

	* gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
	error reporting

	* gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting

	* gdk-pixbuf-io.h: Add GError** to load_increment and load
	methods

	* gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
	a G_FILE_ERROR if we fail to write or close the file.

	* gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
	G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
	the GError naming rules. Add GError** to load functions.
