QElapsedTimer uses a monotic clock on all relevant systems
and is thus invarant against date/time changes (while the
bug was likely caused by daybreaks)

Add an option to kcmcompositing in the 'Advanced' tab, to enable or
disable color correction. It is specified that it's experimental and it
needs Kolor Manager.
Before painting for a particular screen, ColorCorrection::setupForOutput
should be called.
A screen property is added for WindowPaintData.
In kwinglutils, The fragment shaders are intercepted before being
compiled and they get a couple of lines of code inserted in order to do
the color correction. This happens only when color correction is enabled, of
course.
For D-Bus communication with KolorServer, everything is async.
The implementation basically manages a set of color lookup tables for
different outputs and for different window regions. These are taken via
D-Bus. Each lookup table has around 700 KB.
This commit reintroduces the changes from the former merge with the
"color2" branch. In this form, it can be easily reverted.

This was originally added by d467fc1bdbcf69bd6ef213bd909633c2edfb6878,
to prevent alpha ending up to be 0 with blending disabled. Apparently,
that was a driver issue that is no longer present.

This merge is incomplete and it does not include the review number of
the associated review request. It should have been pushed as a single
commit, because the merged commits were not intended to be published in
their form.

This implements an optimization similar to one in compiz which defers updating
the backing X window during a window move until the move is terminated. This
helps alleviate some choppiness when using composite + vsync.

A decoration can provide the AbilityAnnounceAlphaChannel in addition to
AbilityUsesAlphaChannel. If this ability is provided the decoration can
enable/disable the use of the alpha channel through setAlphaEnabled().
The base idea behind this mechanism is to be able to tell the compositor
that currently alpha is not needed. An example is the maximized state in
which the decoration is fully opaque so that there is no need to use the
translucency code path which would render all windows behind the deco.
In addition also the blur effect honors this setting so that behind a
known opaque decoration no blurring is performed.
Oxygen is adjusted to disable translucency in maximized state and Aurorae
is adjusted to allow themes to enable/disable translucency. For Plastik
translucency and with that also blurring is disabled.

Port the KCM to use KConfigXT which means that the complete custom code
for loading, saving and setting to defaults can be dropped.
Also in the effect in brings some advantages as we basically get compile
time checks whether the accessed config is named correctly.
The saved values for translucency are now UInts in [0,100] instead of
doubles in [0.0,1.0], so an update script is needed.

The current API call to animate a window does not feel very JavaScripty.
Therefore a new method "animate" is added to the global scope, which
takes a JavaScript object of the following structure:
{
window: EffectWindow, /* the window to animate, required */
duration: int, /* duration in msec, required */
curve: QEasingCurve.Type, /* global easing curve, optional */
type: Effect.Attribute, /* for first animation, optional */
from: FPx2, /* for first animation, optional */
to: FPx2, /* for first animation, optional */
delay: int, /* for first animation, optional */
animations: [ /* additional animations, optional */
{
curve: QEasingCurve.Type, /* overrides global */
type: Effect.Attribute,
from: FPx2,
to: FPx2,
delay: int
}
]
}
At least one animation needs to be specified either on the root level
or in the array of animations. Curve is the only property on root level
which is used in the animations, if not provided.

Use XDamageReportNonEmpty instead of XDamageReportRawRectangles.
In XDamageReportNonEmpty mode the server generates a single damage
event when the damage state transitions from not-damaged to damaged.
When the compositor is ready to paint the screen, it requests the
damage region for each window and resets the state to not-damaged.
With XCB we can request the damage regions for all windows in a
single roundtrip, making this the preferred mode.
This should reduce the number of wakeups and the time spent
processing damage events between repaints.
oxygenexceptionlistwidget: better check index validity in "edit" method. Also update buttons status after removing items, since
apparently selectionChanged signal is not sent by Qt.
