Toplevels are now true layered windows that are moved, resized and repainted via UpdateLayeredWindow() API call. This achieves transparency without any extra effort, and prevents window size and window contents desychronization (bug 761629). This also changes the way CSD windows are detected. We now use window decorations to detect CSDiness of a window, and to decide whether a window should be layered (CSD windows should be) or not. Decorations are now stored in the window implementation, not as a quark-based property of the window-as-gobject. https://bugzilla.gnome.org/show_bug.cgi?id=748872
