Historically, activities 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, updating the system mime types database via the
update-mime-database tool.

When update-mime-database is executed during packages creation, creates
a new mime types database, therefore these database files are included
among the package files.

This happens for every activity that includes an mimetypes.xml file,
and therefore, multiple activity packages contain the same database files,
colliding on installation time and preventing the packages from being
installed.

This patch provides a way to prevent this from happening, by passing a
new "--disable-update-mimedb" argument to "setup.py install". Note that
sugar shell already provides an identical solution.

With this argument, packaging files can keep using bundlebuilder and
manually running update-mime-database, in later packaging stages, ie.,
postinst in debian.

This approach is backwards compatible and it is optional, therefore other
programs using "setup.py install" will no be affected.

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()

This change remove duplicated code

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 invoker is not used anymore, now is replaced by TreeViewInvoker.

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.

…/godiard/sugar-toolkit-gtk3 into godiard-cell_renderer_icon_optimizations

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.

It does not matter if the file cannot be removed, so do not report it.

Instead of calculating them on each render.  The cache is removed when
the size is changed.

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
[1].

FIXME, to be written.

Gtk has deprecated gtk-icon-get-attach-points on version 3.14
We need that information to place pur badges,
this fix read the information from the .icon file

[1] https://developer.gnome.org/gtk3/stable/GtkIconTheme.html#gtk-icon-info-get-attach-points

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.
