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. REVIEW: 110578
