Vlad Zahorodnii 9acf04e2b7 Refactor Toplevel::opacity
The major difference between this version and the previous is that kwin
no longer forwards the opacity to the app window if it runs as a
window window manager and a compositing manager. As Keith Packard said [1]

There are a couple of reasons to do so: (a) simplifies code, (b) we don't
temper with opacities on override-redirect windows.
