Load the brightness module earlier in the shell startup process
in order to restore the brightness level before any other screen
shows up, ie., the intro screen.

Watch the specific brightness file instead of watching the whole
device directory and drop the use of WATCH_HARD_LINKS because is
not necessary.

This patch fixes the brightness monitor in Fedora 18.

…s/sugar into samdroid-apps-overlay-scroll-try3

This commit disables overlay scrolling in Sugar.  Although this should
be set in the sugar theme, that is not possible.

Setting the environment variable disables the overlay scrolling for
both Sugar Shell and all sub processes (eg. activities).

By setting an environment variable, this is ignored by Gtk versions
less than 3.16.

For consistency with other modal dialogs such as view source and control
panel, add a handler to translate escape key into stop button.

On most XO laptops the firmware version doesn't have the engineer's
build number appended, and this results in "Q7C05   with 0.5.01" shown.

Strip the trailing whitespace before using the version number.

Change the star color on hovering cnfuses to the user,
because think the favorite state has changed.
This can be seen in the activities list view, in the Journal listview,
and in the Journal detail view.

Now the palette is created by the treeview, we don't need
signals in the icon.

These changes were introduced with the TreeViewInvoker

The signals datail-clicked and volume-error, now are triggered
in the TreeView class, and need be connected.

Use the TreeViewIvoker, need move the creation fo the palettes,
from the CellRendererIcons to the TreeViews.
This simplify the code, and allow create the palettes only in the moment
that is needed. In particular, in the Journal, the palette creation is expensive,
and previously was created in the moment the mouse was over the icon,
not matter if the palette was used or not. This was the origin of bugs like [1]

[1] http://bugs.sugarlabs.org/ticket/4343

Using the ScrollingDetector, we can avoid expensive drawing
operation unneded while scroll in the CellRendererIcons.
This patch attach the scrolling detector to the treeviews in the Journal
and in the Activities List.

Connect to Brightness.changed_signal to update the progress bar if
the brightness values changes externally, ie., because of changes
made by power manager or captured control keys.

Add a delay to the changes triggered by the progress bar in the display
frame palette.

This is necessary because calling to external tool is slow and because we
do not need to update the screen brightness for every bit of increment,
while the bar is still being changed.

Add a new globalkey file to implement brightness controls with the
keyboard. This is necessary for detecting XF86MonBrightnessUp and
XF86MonBrightnessDown events in standard laptops.

Use a GFileMonitor to track external changes done to the backlight
device.

This is required for detecting changes made to the device from external
power managers and to workaround missing keyboard events in the XO.

Ignore "external" changes triggered internally.

Add a new gsettings scheme key for saving and restoring brightness
values between sugar shell sessions.

Store values that are set by the user and do not store changes while
is still changing, in order to avoid unnecessary calls to gsettings.

Add a new model which acts as a general backend for modifying
and tracking the brightness of the screen. This model uses
sugar-backlight-helper to interact with the backlight device.

Signed-off-by: Martin Abente Lahaye <tch@sugarlabs.org>

Add two CLI tools, the first one called "sugar-backlight-setup",
and the second one "sugar-backlight-helper".

The setup tool finds the backlight device and creates a symlink
under /var/run/ so it can be later used by sugar. The helper tool
allows sugar to interface with the backlight device.

Both tools are wrapped with polkit execution to access privileged
resources without root access.

Examples:

$ pkexec /usr/bin/sugar-backlight-setup
$ /usr/bin/sugar-backlight-helper --get-brightness
$ pkexec /usr/bin/sugar-backlight-helper --set-brightness INT

…ozl-2015-05-dcon

Sugar asks olpc-powerd to unfreeze the display once startup is
complete.  On platforms without olpc-powerd, this causes:

	ERROR dbus.proxies: Introspect error on
	org.freedesktop.ohm:/org/freedesktop/ohm/Keystore:
	dbus.exceptions.DBusException:
	org.freedesktop.DBus.Error.ServiceUnknown: The name
	org.freedesktop.ohm was not provided by any .service files
	ERROR root: Cannot unfreeze the DCON

Remove this logging, by detecting powerd before resolving the interface.

Remove the DCON concept from main.py, by changing method names, so that
the implementation details are hidden in model/screen.py

Tested on XO-1 with Fedora 18.

Tested on commodity hardware with Ubuntu 14.04.2 LTS (Trusty).

The BundleLauncher is a dbus service served from within the sugar
shell process.  The BundleLauncher service lets activities launch
other activities, with a given bundle_id, mime_type or object_id.
