   Scenen er 16:9 på bred skjerm og vokser i høyden på smal, slik at
   lysbildene kan leses på telefon. Alle mål på bred skjerm går i --u,
   som er 1 prosent av scenens bredde, så hele bildet skalerer som ett.
   Hvorfor ikke transform: scale: da blir teksten ti pixler på en telefon
   og det er ingen vei ut. Med --u kan smal skjerm velge egne størrelser.
