This new invoker is able to handle all the palettes on a treeview,
removing the need of one invoker per cell renderer (CellRendererInvoker).
This simplifies the code and makes it more efficient.
Also removes the logic from the CellRendererIcon, which
should only care about drawing itself. [1]
Is important to note than in Gtk3 a CellRenderer is not a GtkWidget
then can't know when the mouse is over it or have the usual events
used by other invokers, making the implementation CellRendererInvoker
very complicate.
This commit also removes the invoker of CellRendererIcon.
The ScrollingDetector logic is simplified too,
because now there are only one invoker instead of one by renderer
and the example code updated.

Detecting if the treeview is scrolling we can improve the performance of
the CellRendererIcon by avoiding unneeded calculations.
The example scrollingdetector.py shows how this can be used. The
changes are backward compatible.

On commodity hardware without olpc-powerd, there is unnecessary
filesystem access.
On XO laptop hardware there are unnecessary errors in log for every
object delete:
ERROR root: Inhibit Suspend: Could not delete file
/var/run/powerd-inhibit-suspend/1773
Exception AttributeError: "'NoneType' object has no attribute
'endswith'" in <bound method PowerManager.__del__ of
<sugar3.power.PowerManager instance at 0xa15962c>> ignored
The Clock activity in speaking mode is a good reproducer.
Following changes are made:
- move the directory check to __init__, and set self._path to None if
olpc-powerd is not present,
- on inhibit_suspend, use self._path, which avoids a check of the
directory,
- on restore_suspend or __del__, avoid a call to os.unlink if
olpc-powerd is not present.
Use a more efficient method to check if the pointer is inside the cell,
because we have the cell_area in the do_render method.

This commit adds the `launch_bundle` function in `sugar3.activity.
activity` which accesses the same function in the shell is over dbus.
This is means the shell process launches the bundle. Activities
should not launch child processes as per the Rainbow security model

If a translator add a '\n' char in the summary translation
ConfigParser can't parse the linfo file.
Remove them when the file is created and show a message to warning
to the developer.
When we ported sugar to Gtk3 we removed the support of the fields
exec and service_name due they were deprecated for a long time [1].
But this is still a problem in deployments, and we already added
compatibility for the service_name field.
Here [3] there is a long thred were we discussed this issue.

As described in SL#4307 Gtk.Clipboard.set_with_data is not
introspectable, therefore it can't be accessed though python
Gtk bindings.
Therefore, as a workaround for this issue, we provide acesss
to this method though a custom SugarExt binding.
This solution uses Carlos Garnacho annotations as described in
https://bugzilla.gnome.org/show_bug.cgi?id=656312#c18
Fixes SL#4307.

Now when the espeak plugin is not installed there will be an
error (logging.error) in the log. Instead of the ugly message
of Gst
Also, if Gst isnt installed it debug a error too.
Fixes#3345
The BundleBuilder currently crashes on a malformed translation file. This is
good for humans (makes them fix their issues) but crashes bots who need it
compiled and don't care about that single translation file.
This patch adds a --no-fail option which stops the builder from crashing
