In the GTK3 port we mistakenly moved from using the EggSMClientXSMP
class to the (stub-like) EggSMClient base class for Sugar's XSMPClient
class, instantiated for every activity.
This meant that the GTK3 activities weren't registering with the
session manager, meaning that they won't automatically save their work
when the user shuts down, and they can't inhibit shutdown, etc.
Restore this functionality by adding the appropriate header so that
EggSMClientXSMP is introspectable, and then use it from the Python code.

This adds a property that indicates that a Palette should
behave in a locking manner. The behaviour is the same
as with the secondary Toolbars: when you hover over the invoking
widget the Palette will popdown and react to mouse movements,
leaving the invoker area or the Palette itself will popdown
the Palette again. When you click the invoking widget
the Palette will be locked. You have to unlock it again
to pop it down.
This patch makes the DescriptionButton and the Colorbutton
work.
If the DescriptionButton or the Colorbutton are placed in
the primary toolbar they will share the locked state with
the secondary toolbars. Only one can be locked at a time.
When a secondary toolbar is unlocked we do force that the
open Palettes are closed. Having a locking Palette in
a subtoolbar will also work (Activity Toolbar case or
ColorButton case in a few examples). There is no state
sharing implemented here at the moment, but so far we
do only have cases with one lockable Palette in a
subtoolbar.
This will also fix the case where we want to use the
OSK to edit the description of the activity SL #3887.

A new API is provided: PaletteMenuBox is a container to be used in
Palette.set_content(). This is to hide the implementation details and
set the corresponding paddings and sizes.
Usage:
box = PaletteMenuBox()
palette.set_content(box)
Then we can append items to it, like:
item = PaletteMenuItem(text_label, icon, xo_color=xo_color)
box.append_child(item)
separator = PaletteMenuItemSeparator()
box.append_child(item)
We can also append any widget, and the box will handle the paddings:
box.append_child(widget)
style.DEFAULT_PADDING for horizontal and vertical padding is the
default. But can be overriden:
box.append_child(widget, horizontal_padding=0, vertical_padding=0)
Details:
- move palettemenuitem.py to palettemenu.py
- Width of palette: make it a minimun size of 3 Sugar grid cells.
- Padding of content, secondary box: we need top and bottom padding,
which can be set when packing the items container inside the
secondary box.
- Padding of menu items: needs to be just for left and right, so move
the padding to a new horizontal box.
- Padding of separators: unlike GtkSeparatorMenuItem, GtkSeparator
doesn't support padding. But we can wrap it in a GtkEventBox and
force the height of the widget there.

This one is tricky because where the CellRendererInvoker is
used (Home View activity list and Journal list view) we do
use Palettes based on a GtkMenu. In the Journal list view
this Palette has submenus so it can not be easily replaced
with our custom Palette. That is why I am trying to make this
case work with a GtkMenu.
When the Palette does pop up it grabs the focus. This means that
the invoker does not see a TOUCH_END event. Same is the longpress
controller that is why we have to reset the controller when
the long-press is detected, otherwise it is not usable a second
time.
The default behavior of a GtkMenu is that it does pop down
on a long press/release event. So when doing a long press
on the icon the Palette was popping down directly. We can
stop this by listening on the button-release event in the
Menu and return True when the event happens in the invoker
coordinates.
Finally there are several issues with motion events: in the
invoker we listen to motion events on the treeview in order to
be able to popup/popdown the Palette on hovering over the
icon. This event is triggered as well when the icon is
tapped. We do check the origin of the event and do not trigger
the enter/leave when originated from a touchscreen. We do setup
the path for the CellRenderer however.
The second case where the motion events are triggered is
when you tap somewhere in the Palette when it is up. For
example you want to get to one of the submenues. Since the
Palette tracks motion events to work for the hover case [2]
we do get a leave event when the Palette is tapped and the
Palette does pop down. Same here, we check if the event
originated from a touchscreen and do discard it in that
case.

The ShareButton, which derrives from the RadioMenuButton, had the
desired behavior already overriding the on_clicked method, we
do this now in the invoker.
The DescriptionButton did only handle the popup part so far, with
this change the Palette will also popdown when the button is clicked
and the Palette is up.
Since both are Toolbuttons we have to set the hide_tooltip_on_click
property to False otherwise the popdown part would not function, see

The WidgetInvoker will decide if a long press has been made
or not. We watch out for TOUCH_END events and when a long-press
event has been seen before we stop further propagation of the
event, hence there won't be any button-release or clicked
events available to the user of the widget.
There are several widgets using the WidgetInvoker, and those
handle differently touch events. The GtkButton does have a widget
implementation to handle touch events, it does stop further
propagation and emits the pressed/released signal for further
consumption [1]. We will not get a button-press/button-release
event for a touch event in this case.
The default behaviour for widgets e.g. a TreeView is to transform
the touch events into pointer events [2], for those widgets we do get
a button-press/button-release event for a touch events.

-----
v2: Fixed comment based on manuq feedback, and add a note
about the non working drag and drop.
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.
