Rational behind this change is that displayWidth and displayHeight are X specific API calls in kwinglobals. For the future it's easier to only rely on functionality which goes through the EffectsHandler API which allows easier adjustments in KWin core. displayWidth() and displayHeight() are only used to get the size or the complete rect of all screens. This is also provided by: effects->virtualScreenGeometry() or effects->virtualScreenSize() REVIEW: 116021
