7431c4d611 magnifier: Using properly 'color-saturation'
As description of the setting says, color-saturation ranges from
0.0 (grayscale) to 1.0 (full color), but the real outcome was the
opposite. The reason is that clutter provides a desaturation effect,
and color-saturation was passed directly to that effect. This patch
renames the effect and compute the desaturation value.

8754b2767c Add a grayscale effect
This commit adds a grayscale effect to the magnifier, similar to
the lightness, brightness and contrast effects that are already there.

The effect is configured with the
org.gnome.desktop.a11y.magnifier.color-saturation setting, which
can take values from 0.0 (grayscale) to 1.0 (full color).

Based on a patch by Matthias Clasen <mclasen@redhat.com>

723a1c843a Refactor show()/hide() sequences
We seem to have a lot of code that does something along the lines of:

    if (condition)
        actor.show();
    else
        actor.hide();

ClutterActor already has such a thing for exactly this purpose: the 'visible'
property. Use it instead of the mess above.

3631983de5 magnifier: Adjust for removal of 'show-magnifier' key
gsettings-desktop-schemas had two conflicting settings for showing
the magnifier: 'show-magnifier' in org.gnome.desktop.a11y.magnifier
and 'screen-magnifier-enabled' in org.gnome.desktop.a11y.applications.
The former has been removed in favor of the latter, so adjust to this
change.

978cf9d3ab Fix redundant calls to global.get_pointer()
Since we are keeping a current pointer position anyways, we
don't have to continually call global.get_pointer() which is
a round trip to the magnifier; make ZoomRegion simply fetch
a current position stored in the Magnifier object.

96fb6d8f16 Improve the algorithm for proportional mouse tracking
Change the proportional algorithm so stop moving the zoom region
when cursor is in a "padding region" at the edge of the screen.
(The padding region is a 10th of the screen at 2x zoom, and smaller
for higher zooms.)

Based on earlier versions from Jon McCann and Florian Muellner.

c5c66ceb98 Refactor Magnifier.ZoomRegion to avoid permanent Clutter.Clone
This basic point of this change is to avoid always creating a
hidden Clutter.Clone actor for the default present-but-not-active
zoom region. The position of the viewport and region of interest
are now stored in member variables, and the actors are only created
and updated when the region is active.

Other significant changes:

 * Unused public functions are removed or made private
 * The mouse tracking position is immediately  updated when options
   like the zoom are changed, not just on the next mouse motion.
 * ZoomRegion.setROI() now updates the zoom, not just the position;
   a FIXME is added to the D-Bus interface for a place where the
   D-Bus interface contains duplicate possibly conflicting information
 * Lens-mode is now only effectively off when the magnifier is
   fullscreen, instead of actually modifying the member variable;
   this makes things work properly when changing out of full-screen
   mode.
 * When the clamping to screen edges is turned on, we now immediately
   clamp.
 * The handling of setting the position to fullscreen as compared
   to just setting the viewport to fullscreen is untangled.

6ea18136ac Add Universal Access status indicator
Introduce the Universal Access status indicator as designed, modeled
after the similar UI provided by g-s-d. This indicator allows the user
to change rapidly the keyboard and mouse behaviour (sticky keys, slow
keys, bounce keys, mouse keys), as well as the enabled ATs (magnifier,
screen reader, screen keyboard) and the HighContrast Gtk theme.

e88f08072c Bug 622414 - Port magnifier to GSettings
The Shell is the only user of the magnifier, so there's no
reason to keep using GConf for its settings. Since it's a
session-wide tool, use a distinct schema,
org.gnome.accessibility.magnifier, stored in
/desktop/gnome/accessibility/magnifier just like before.
Put these settings in a separate schema file for clarity.

Old enums in GConf were stored as integers, we now use the
facilities provided by GSettings to save them as strings,
and convert them to integers automatically thanks to the
mapping stored in the schemas. Remove hard-coded default values,
which we can get from the schemas.

2799327c84 Migrate to GSettings
Use GSettings for all Shell configuration. GConf is kept to read
configuration from external programs (Metacity, Nautilus and Magnifier),
but ShellGConf is removed because it's mostly useless for the few calls
we still have. Also get rid of unused GConf code in ShellAppSystem.

A basic GConf schema is still used to override Metacity defaults and
configure Magnifier in a system-wide fashion. GConf is also used as
GSettings backend via the GSETTINGS_BACKEND environment variable.
All of this will be removed when these programs have been ported
to GSettings and able to use dconf.

GLib 2.25.9 is required. Schemas are converted to the new XML format,
and compiled at build time in data/ so that the Shell can be run from
the source tree. This also requires setting the GSETTINGS_SCHEMA_DIR
environment variable both when running installed or from source tree,
in src/gnome-shell.in and src/gnome-shell-clock-preferences.in.

703b21cef0 Don't use double quotes for things that don't need to be translated
This is our convention.

The only exceptions are double quotes for words in comments that give
them a special meaning (though beware that these quotes are not truly
necessary most of the time) and double quotes that need to be a part
of the output string.
