Your eyes are bloodshot.

Your mouth starts to foam.
Your hands are shaking.
You know your need your fix.
NEED MORE ABSTRACTION!

This comes from an excellent idea by Tim Janik (timj@gtk.org) to
hook to the last unref operation.
* gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
function to set the last unref handler for a pixbuf.
(gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
It calls the pixbuf's destroy notification function and frees the
GdkPixbuf structure itself.
(gdk_pixbuf_unref): Use the last unref function of the pixbuf if
available.
* gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
for the last unref handler and its user data.
* gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
g_new0() to allocate the pixbuf.
* gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
Fixed the call to gtk_signal_new() for the "frame_done" signal; it
was not specifying the `frame' argument.
* gdk-pixbuf/gdk-pixbuf-animation.c
(gdk_pixbuf_animation_get_width): Fixed docstring.
(gdk_pixbuf_animation_get_height): Likewise.
(gdk_pixbuf_animation_get_num_frames): Likewise.
(gdk_pixbuf_animation_get_frames): Likewise.
* doc/gdk-pixbuf-sections.txt: Updated with the new functions and
types.
* doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
* doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
* doc/tmpl/refcounting.sgml: Updated with the information about
the last unref handler.
* doc/tmpl/*.sgml: Markup tweaks.
* gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
update the libtool version number for libgnomecanvaspixbuf as
well.
(libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
as well, or the old ones won't work with the new stuff. Also,
renamed the modules as follows.
* gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
modules are called "libpixbufloader-<format>.so" instead of
"libpixbuf-<format>.so". They needed renaming so that the new
loaders won't overwrite the old ones; even with the versioning
stuff, the new .so symlink to the .so.1.0.0 would overwrite the
old real .so file.
