Havoc Pennington e0fee22e78 Add built marshaller files to support GdkPixbufLoader signals 
2001-01-22  Havoc Pennington  <hp@redhat.com>

	* Makefile.am: Add built marshaller files to support
	GdkPixbufLoader signals

	* gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
	GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
	module location, rather than acting as a fallback, because we are
	using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.

	* gdk-pixbuf.h: include gdk-pixbuf-loader.h

        * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
	from gtk, and add error to close(), because stop_load may do
	parsing of the image.

	* pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file

        * io-*.c: make individual operations static, and add fill_vtable
	functions which are exported. Fix the collection of type warnings
	that surfaced, including a number of functions that didn't
	properly take a GError and some that weren't
	const-correct. Involved adding error handling for a few loaders.

	* gdk-pixbuf-io.h: Add error reporting to stop_load function

	* gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
	a function that fills in the GdkPixbufModule vtable, instead of
	looking up all the image functions individually; this means we
	can get type safety within modules for the loader functions.
	Also it means you don't have to keep the statically compiled and
	GModule versions in sync.

	* test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()

	* make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()

	* gdk-pixbuf.h: nuke gdk_pixbuf_init()

	* gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
	() here

	* gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here

	* gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
	g_type_init() here


2001-01-22  Havoc Pennington  <hp@redhat.com>

	* demos/testanimation.c: fix to reflect gdk-pixbuf changes

	* demos/testpixbuf.c: fix to reflect gdk-pixbuf changes

	* gtk/gdk-pixbuf-loader.c, gtk/gdk-pixbuf-loader.h:
	Remove, move back to gdk-pixbuf

	* gtk/gtktextiter.c, gtk/gtktextiter.h: add sentence equivalents
	to all the word functions

	* gtk/gtktextview.c (gtk_text_view_start_cursor_blink): return
	before doing anything on NULL layout or if we don't have the focus

	* gtk/testtext.c (fill_example_buffer): "justification"

	* gtk/gtktexttag.h, gtk/gtktexttag.c: change the tag attribute
	to be called "justification" not "justify"

	* demos/gtk-demo/textview.c (create_tags): "justification"

	* gtk/gtktextlayout.c (set_para_values): Handle char-wise wrapping
