Wed Jun 21 16:38:13 2000  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf/* docs/reference/gdk-pixbuf/*: Welcome aboard,
	gdk-pixbuf.

	* gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
	fixups for GObject.

	* gdk/Makefile.am gdk/gdkpixbuf-render.[ch] gdk/gdkpixbuf.[ch]: Bits of
	gdk-pixbuf with GDK dependencies moved into GDK.

	* gtk/Makefile.am gtk/gdk-pixbuf-loader.[ch]: Temporarily
	move gdk-pixbuf-loader here until GObject has signals.

	* demos/: New directory of demos. Move demos from
	gdk-pixbuf here.

	* demos/pixbuf-init.c: Small bit of code to check for
	loaders in ../gdk-pixbuf/.libs/gdk-pixbuf, and if found,
	set GDK_PIXBUF_MODULEDIR appropriately.

	* gdk/gdkcompat.h: Remove GDK_DRAWABLE_PIXMAP compat
	define which no longer makes sense.

* gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),

	* gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
	Now that Owen explained the algorithm, I think I implemented it
	right for the cases where the destination pixbuf is not opaque.
	The test does seem to confirm it.

	Added some tests of composite to highlight problems in the old
	implementation. These tests run without any user interaction.
	Just do "make check".

	* gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
	(composite_pixel), (composite_line): Fix composite to do a textbook
	"A over B" composite. This was clearly the intent, and it was easy
	to fix the code to do it. (Note to those that read my earlier tries
	at a patch; this version fixes typos that were present in all
	my patch attempts. I checked the final version by adding more tests.)

	notification function.

	a pixbuf.

	* gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
	bits_per_sample argument; currently only 8 bits per sample are
	supported.

	New accessor.
	(gdk_pixbuf_frame_get_x_offset): New accessor.

	* gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
	an lvalue.

	* README: Updated.

	* gdk-pixbuf-config.in (--libs): We no longer require libart.
