The wm module in sugar-toolkit-gtk3 has been reimplemented
in C and made available through introspection. The same was
hard to achieve directly using the Gdk API.
We can drop wm.py and the wrapper around gdk_property_change.

gobject introspection bindings for librsvg have been pushed to librsvg
master [1] in 2.35.0, which solved [2]. We only have slight adopts to
make in our usage, for example we can not pass the data property
to the default constructor anymore and get_width and get_height is not
available anymore for the handle, but we can use the properties
instead.
The sugar-toolkit-gtk3 and therefore Activities that have been ported
to it do need a version of librsvg >= 2.35.0 to be able to work,
which ships for example with Fedora 17.

Moving from GTK2 to GTK3 has presented various challenges regarding
palettes.
In GTK2, we were able to access some internal API of the GtkMenu class
and use it to embed a GtkMenu in a regular window. As of GTK3, that API
has become private and we can no longer access it.
We still want to use GtkMenu for the advanced functionality it provides
(multiple-level menus, keyboard navigation, etc), but we are now limited
to popping it up with its own (internal) window, rather than being able
to pack it into one of our own.
Our palettes can historically be used either as a menu, or as a general
area where widgets can be added, or both. The new restrictions upon
GtkMenu force some changes here, but we work hard to stick to the old
API as far as possible.
A Palette instance now acts as a controller of either a "window widget"
(where any type of widget can be displayed as usual) or a "menu widget"
which just pops up a GtkMenu. A Palette defaults to the window mode, but
dynamically switches to menu mode if/when the user attempts to access
the menu element.
As a result of this, palettes can now pack either a user-defined collection
of widgets, or a menu, but types can no longer be mixed. This should
only affect a handful of palettes which will need to pick a single
approach and convert to it.
Some further challenges are presented by the fact that GtkMenu performs a
grab on the whole screen, meaning that all input events are delivered to
the GtkMenu widget. Through some careful event filtering and examination
of the mouse cursor position we are still able to determine when the mouse
has entered or left the invoker or menu areas.

Probably needs cleaning up a bit. And we use pygtk-codegen, ugh...

This makes sugarext accessible through introspection. It is used
from the shell (key grabber, sound volume management) and the
shell session management.
Making the sugarext introspectable was done following the
descriptions at: http://live.gnome.org/GObjectIntrospection#Using_GI
