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.

It appears that we're accidentally choosing an MSAA config with the
Intel driver in Mesa 9.0. So change the algorithm to take the values
of GLX_SAMPLES and GLX_SAMPLE_BUFFERS into account.
Found by Kenneth Graunke.
According to Pierre-Loup Griffais (Plagman on IRC) this is causing
choppy VDPAU video playback when compositing is enabled.
Removing these calls doesn't seem to cause any regressions, and the
commit that added them doesn't give a reason. So let's just get rid
of them for now.
