Subject: [PATCH] Zug-Symbole: kein Quadrat mehr beim Rauszoomen, kleiner bei
 kleinem Zoom
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Der Icon-Rand war breiter als das SDF-Feld und füllte bei kleinem
Zoom das ganze Bild. Rand skaliert jetzt mit der Symbolgrösse.
