/*
 * GEOMANCY watch face
 *
 * A simple and straightforward watch face for the ancient Eastern geomantic divination system
 * of I Ching and the western system of "Geomancy". It is an optional addition to the Toss Up
 * Face.
 * 
 * The LIGHT button toggles between the two systems of geomancy.
 * 
 * The ALARM button casts an I Ching hexagram or Geomantic figure based on drawing virtual
 * stalks from the True Random Number Generator in the Sensor Watch.
 * 
 * The figures are flipped 90 degrees clockwise, so the left side is the bottom and the
 * right side the top.
 * 
 * LONG PRESSING ALARM toggles the display of the King Wen sequence index for the cast I Ching
 * Hexagram (https://en.wikipedia.org/wiki/King_Wen_sequence )or the abbreviated name for the
 * cast Geomantic Figure:
 * 
 * GF - Greater Fortune (Fortuna Major)
 * LF - Lesser Fortune (Fortuna Minor)
 * PO - Populus
 * VI - Via
 * AL - Albus
 * CO - Conjunctio
 * PA - Puella
 * AM - Amissio
 * PR - Puer
 * RU - Rubeus
 * AQ - Acquisitio
 * LA - Laetitia
 * TR - Tristitia
 * CA - Carcer
 * HD - Head of the Dragon (Caput Draconis)
 * TD - Tail of the Dragon (Cauda Draconis)
 *
