fix some shell typos

2001-05-04  Havoc Pennington  <hp@redhat.com>

	* configure.in: fix some shell typos

	* gtk/gtkcolorsel.c (gtk_color_selection_destroy): warning fix

	* gtk/gtkimage.c: handle animations

	* gtk/gtkcheckbutton.c (gtk_check_button_size_request): request
	border_width * 2, not just border_width

	* gtk/gtkscale.c: add "format_value" signal to allow people
	to override the way values are drawn.
	(gtk_scale_get_value_size): fix width/height mistake,
	and compute size from actual displayed text, not
	from made-up text.

	* gtk/gtktexttag.c (gtk_text_tag_class_init): fix return type in
	signal registration

	* tests/testtext.c: Add "Remove all tags" menu item for testing

	* gtk/gtktextbuffer.c (gtk_text_buffer_remove_all_tags): implement

	* demos/gtk-demo/main.c (main): add hack so we can find modules
	without installing gtk

	* demos/gtk-demo/textview.c (insert_text): demo font scaling

	* gtk/gtkcellrenderertext.c: Add "scale" property (font scaling
	factor)
	(gtk_cell_renderer_text_set_property): remove some bogus
	g_object_notify

	* gtk/gtktexttag.c: add "scale" property which is a font scaling
	factor

	* gtk/gtktextlayout.c (add_text_attrs): add font scale attribute
	to layout

	* gtk/gtktextiter.c (gtk_text_iter_is_start): rename from
	gtk_text_iter_is_first

2001-05-04  Havoc Pennington  <hp@redhat.com>

	* pixops/pixops.c (pixops_process): merge fix from stable: Patch
	 from hoshem@mel.comcen.com.au to fix nonzero X offsets.  Fixes
	 bug #50371.

        * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
	from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
	confusion of using "src" instead of "p".
        (pixops_composite_color_nearest): Use a more accurate (and
	correct, to begin with) compositing method.  This cures checks
	showing through on images with no alpha.

	* gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
	bytes unfilled.

	* gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints

	* gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
	area_updated signal to use signed ints.  Removed animation-related
	signals.

	* io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
	rewrite action

	* gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
	all the pesky details. Remove old frame-based API. Make
	GdkPixbufAnimation an abstract base class, derived by the loaders.

-    The &gdk-pixbuf; library provides a simple mechanism to load and
-    represent animations, primarily animated GIF files.  Animations

+    The &gdk-pixbuf; library provides a simple mechanism to load and represent
+    animations. An animation is conceptually a series of frames to be displayed
+    over time. Each frame is the same size. The animation may not be represented
+    as a series of frames internally; for example, it may be stored as a 
+    sprite and instructions for moving the sprite around a background. To display 
+    an animation you don't need to understand its representation, however; you just
+    ask &gdk-pixbuf; what should be displayed at a given point in time.
