Martin Gräßlin c7262e8bd3 Getter/setters for opacity, saturation and brightness in WindowPaintData 
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.

This commit is the top-most of a patch series to refactor
ScreenPaintData and WindowPaintData. Other related commits are:
