The icon consists of an GtkEventBox and an IconBuffer. The
GtkEventBox is a subclass of GtkBin which has its own window and
therefor is used to catch events for our IconBuffer which does
not have it's own window. The window of the EventBox is
made invisible.
The EventIcon does not emit the 'activated' signal when clicked
anymore, you can listen to 'button-release-event' to know
when the icon has been clicked. The EventIcon uses the
CursorInvoker to invoke a palette the same way as the
CanvasIcon did.
We keep the same API as with the CanvasIcon, only the 'size'
property is changed to be called 'pixel_size' in order to
make clearer which values it expects to be passed. We don't
expect a GtkIconSize to be passed here.
Another option would have been to put a SugarIcon inside a
a GtkEventBox and make the properties available through an
icon property but the API would have not been as nice and
logically it seems to make more sense to have the IconBuffer
being the base for both the SugarIcon and the SugarEventIcon.
This patch has ben developed based on the one that is
used in the shell port.

The create_palette mechanism allows to create
palettes on demand and not for each icon upfront
whether it will be needed or not.
If you hover over an EventIcon and there is no
palette already associated with the Invoker, the Invoker
will call create_palette to see if it can be created
on demand. With this patch the EventIcon will return None
here (see as well CellRendererIcon or ToggleToolButton which
are having the same default behavior).
When subclassing EventIcon the create_palette method can
be overwritten and a Palette returned (see for example
the ActivityIcon in the HomeView).
Without this patch you can see tracebacks when hovering
over the EventIcon because the Invoker tries to call
create_palette.

Position the event box window above the windows of its child, that way
all events inside the event box will go to the event box. If the window is
below, events in windows of child widgets will first go to that widget,
and then to its parents [1].

We do use the EventBox only to receive events, hence the
window that the even box creates should be a GDK_INPUT_ONLY
window, which means that it is invisible and only serves to
receive events [1].

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.

CanvasIcon and CanvasInvoker were removed in a previous GTK3-porting commit
as they were based on hippocanvas.
However, this leaves the toolkit with some missing functionality:
there is no longer a trivial way to show an icon which can receive mouse
events and pop up a palette. Such functionality is used in various
places throughout the shell and activities.
Reimplement this functionality as EventIcon and CursorInvoker.
Instead of reimplementing much of the Icon class (like CanvasIcon did),
EventIcon opts for a more simplistic encapsulation of an Icon object.
This means trivial API changes for CanvasIcon users who must now
use the 'icon' property with the Icon API.

GtkWidget "expose-event" signal has been replaced by
a new "draw" signal [1]. The context is already
clipped [2], so do not base it on the values returned by
get_allocation like before.

The previous set_source_pixbuf() invocation (on a Cairo context) involves
Gdk data types, so in the new introspection world we need to call a Gdk
function rather than operating on the Cairo object (even if Cairo had already
been converted to introspection).

This is only on a best-effort basis; the code will be in a broken state after
this patch and need to be fixed manually.
The purpose of committing the intermediate, non-working output is to make it
reproducible. It's impractical to manually review the changes.
The exact version used was 4f637212f13b197a95c824967a58496b9e3b877c from the
