workspaceAnimation: Add a background

In future we will need to use window clones to better support multiple
monitors. To avoid having to hide every window, show wallpapers behind
the workspace transition: one per monitor.

Put the wallpaper into a separate class right away, later it will be
useful to make the animation per-monitor.
