+* Orientierung des Steinchens durch Unterstreichung abbilden
+Zu Deiner Frage 1: Wie sollen wir es realisieren, dass man weiß, wie herum der
+Braille-Buchstabe zu lesen ist?
+
+Ein waagerechter glatter Strich unterhalb des Braille-Symbols, 3,5- oder
+5,0-mm-Abstand zur dritten, unteren Punktreihe.
+* Mehrere Buchstabenplättchen zu einem Set zusammenfassen zum Drucken
+* Spielbrett entwerfen

-/* Version 3
- Added support for font selection (default is Letters.dxf)
- Added WriteCube module
- Added Rotate for text (rotates on the plane of the text)
- Added writesphere
- Added space= (spacing between characters in char widths) def=1
- Added writecylinder()
