* gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
(i.e. derivation is not allowed, and there are no virtual methods
anyway).
(gdk_pixbuf_preinit): Call g_type_init() here.
(gdk_pixbuf_init): Add a user-friendly init function, for users
of standalone gdk-pixbuf
* gdk-pixbuf-animation.c: Convert to GObject, in the same
way GdkPixbufAnimation was done.
* gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
gdk_pixbuf_finalize() from API, since these are broken and don't
make sense with new GObject stuff.

* gdk/gdkwindow.c (_gdk_window_destroy_hierarchy): Fix bug where
we didn't check window->bg_pixmap != GDK_NO_BG.
* gtk/gdk-pixbuf-loader.c: Change to reflect GObject-ification of
gdk-pixbuf
* gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
(composite_pixel), (composite_line):
* 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.
* gdk-pixbuf/.cvsignore:
* gdk-pixbuf/Makefile.am:
* gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
(load_pixel), (simple_composite_test_one),
(simple_composite_test_one_type), (simple_composite_test), (main):
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.)
