Clients tend to set picture->repeat when not necessary. Most HW cannot 

accelerate repeat NPOT thus triggering software fallback (this is the
    case with gnome desktop for example). This adds a simple optimisation
    to exa that removes "repeat" when it's obviously useless, that is, the
    single picture instance covers the entire rectangle beeing used
