7. Beispiel - Umrechnung
   Gegeben
   Eine drawalbe-ldpi/icon.png Grafik mit der Breite 6 Pixel.
   factor of default low fl = 0,75
   factor of default xhigh fx = 2
   width low wl = 6
   Gesucht
   Die Breite in Pixel der drawable-xhdpi/icon.png Grafik.
   width xhigh wx
   Lösung
   w = w
   wx / fx = wl / fl
   wx = (wl * fx) / fl
   wx = (6*2)/0,75 = 16
   Die Breite der xhigh Grafik ist 16 Pixel.
