window deleted in the first event cycle (before the deleted
signal is bound) - so we add an initialization flag to ensure
the binding happens before the first animation is added

Just like Opacity for transforming only the decoration opacity.
It's an ABI break as the new enum value had to be included as anonther
non-float base value.
Cross fading with previous pixmap is achieved by referencing the old
window pixmap. WindowPaintData has a cross-fade-factor which interpolates
between 0.0 (completely old pixmap) to 1.0 (completely new pixmap).
If a cross fading factor is set and a previous pixmap is valid this one
is rendered on top of the current pixmap with opacity adjusted. This
results in a smoother fading.
To simplify the setup the AnimationEffect is extended and also takes care
about correctly (un)referencing the previous window pixmap. The maximize
effect is adjusted to make use of this new capabilities.
Unfortunately this setup has a huge problem with the case that the window
decoration gets smaller (e.g. from normal to maximized state). In this
situation it can happen that the old window is rendered with parts outside
the content resulting in video garbage being shown. To prevent this a set
of new WindowQuads is generated with normalized texture coordinates in
the safe area which contains real content.
For OpenGL2Window a PreviousContentLeaf is added which is only set up in
case the crass fading factor is set.

Do not schedule repaints in AnimationEffect if there are no animations
going on. If an animation is waiting for starting or kept after ending
the visual appearance is no longer changed, so no repaint is needed.

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)

use monitc clock
The public member variables for opacity, saturation and brightness
are removed in favor for getter and setters. The variables are
moved into a private class. Those are now qreal instead of double.
To make usage inside the effects easier a multiply method is added
which multiplies the current value with passed in factor and returns
the new value in a functional programming style.
