Improve Xubuntu's current plymouth bootscreen. There are a few features we should implement, such as proper wallpaper scaling, and we should probably revisit the boot animation.
Proper wallpaper scaling (Look here for how it could be done)
Implement circular animation instead of the misleading progressbar (pulsing, a spinner etc.) (Again, look here)
Use a symlink to Xubuntu's current wallpaper instead of shipping it inside the theme (unless we want xubuntu's plymouth theme to function independantly as well -> look at packaging recommends and depends)
