Gtk 3.8 introduces the tick callback [1]. This allows widgets to be
signaled before each frame, simmilar to requestAnimationFrame in the
browser.
This patch adds an optional widget argument to the Animator class so
tick based animation can be used. This is much more efficent than
using timeouts, as we get a more appropriate frame rate for the user.

As the ticket describe, create a object in the Journal
is no longer optional. The change do not break activities,
because the optional parameter is not removed, just ignored.
Right now is not possible do "from sugar3.datastore import datastore"
outside of GLib loop, because the import try to connect to a DBus signal,
and throw a exception.
That was not a problem in Sugar, because we always have a Glib loop
on all our activities, but is a problem when we want import the classes
to generate docs with pydoc. Many other classes import datastore,
then this is a blocker.
This patch removes the initialization when imported,
will be done when needed.
To solve ticket #4673, we calculate the palette size using the size
of all the widgets [2]. That solves the problem on Palettes based on
_PaletteMenuWidget but on _PaletteWindowWidget produce a wrong value
when the secondary_label is not null, and as a consequence
the palette position is wrong.
The solution is do the calculation only for _PaletteMenuWidget based
palettes.

With the introduction of 'activate' signal on [1], and the use of that
signal in Sugar Home, we introduced a bug, now, pressing the secondary button
starts the activity instead of open the palette.
This patch solves the issue checking the putton pressed before send the signal.

When is used to clone a activity from sugar,
the options parameter is set to None.
The other uses of no_fail have False as default value
but this case was missing.
The effect of this error is that a .xo is not created in the Journal,
when the user select 'Duplicate' in the View Source window.
Commit a19cf9e changed the logic for handling CanvasIcon clicks. Therefore,
the visual state indicators must be updated to fit the new logic.
Test Case: Hold the mouse down on a home view icon. Move the mouse
in and out of the icon. See that the states correspond with what
happens if you release the mouse.
The mouse detector have a variable to store the id for the timeout.
The stop() method check if the id is null but do not set the id to null
after remove the GObject timeout, then try to remove the timeout multiple times.
The efect can be seen if a user move the mouse slowly over the icons
in the Sugar home, in shell.log we see many lines like:
sugar3/graphics/palettewindow.py:443: Warning: Source ID 2464 was not found
when attempting to remove it
The industry convention for mouse driven menu options is for them
to be activated when two conditions are met:
* a button down event occurs with the pointer inside the option, and;
* a button up event occurs with the pointer inside the option.
This issue was already solved on the PaletteMenuItem,
but the EventIcon have the same problem. This change add a 'activate' event,
that control that the two conditions are meet.
The code in Sugar need use this event instead of button-release-event.
When we use set_icon_widget(), GtkToolButton set a private property
contents_invalid = TRUE [1], and gtk_tool_button_construct_content [2]
is called. Then if the label widget not exist, a GtkLabel is added.
This is a problem for us, by example in the Clipboard buttons in the frame.
By adding a empty Gtk.Box instead of a label, we avoid the label creation.
But as this is a internal implementation of Gtk, can change in the future,
in fact the issue is not visible with Gtk < 3.16
This patch is based in a pr sent by Sam Parkinson

When a programmer need open one activity from other [1]
usually need display in the user interface information about the activity
to open, like the name or the icon.
This method allow get this information, previously only available on jarabe.

The palette using a Gtk.Menu, had a separator displayed using a custom widget,
but that was not well displayed (the line didn't had the palette width
due to margin on the palette) and was broken on Gtk >= 3.16
Instead of use that widget to draw the separator line between at the bottom
of _HeaderItem, as we do with the toolbar buttons when the palette is displayed.
A group of kids from the OLPC project in Caacupe have translated both
the sugar shell and the sugar gtk3 toolkit to Guarani. They are also in
the process of translating sugar activities [1].
This patch add the gn entry to the LINGUAS file so the gn.po file can be
properly installed, as already is being done with the sugar shell.

Historically, distro packagers have been using bunblebuilder, via
"setup.py install", to populate packages directories and files.
The install procedure uses ActivityBundle.install_mime_type to install
custom mime types, by creating symlinks and updating the system mime
types database via the update-mime-database tool.
When ActivityBundle.install_mime_type is executed during packages
creation, the symlinks end-up broken in the final package and the use
of update-mime-database populates the final packages with a new copy
of the database files which could clash with the system copy.
This patch adds a new option, called --skip-install-mime to "setup.py
install" to skip the execution of ActivityBundle.install_mime_type and
avoid the issues mentioned above.
Activity packagers should use this new option. The creation of symlinks
and the execution of update-mime-database should be done in post install
packaging steps.

If is not initialized, the check for the espeak plugin will fail.
This patch also check for the espeak plugin at the beginnig
avoiding check every time the function enabled() is called.
There are two different palette widgets in Sugar.
_PaletteMenuWidget is a Gtk.Menu and _PaletteWindowWidget is a Gtk.Window.
Only the palettes where the widget is a Gtk.Window can do present()
After add the directory to the IGNORE_DIRS array,
we need make the standard procedure to get the list off files
for the bundle, get_files_in_git honor the configured ignored
files and dirs. That was not a problem until now,
because that files was already not added to git,
but in the case of the screenshots, are included in git,
but we don't want include them in our bundles.
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.
[1] https://developer.gnome.org/gtk3/stable/GtkCellRenderer.html
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.
