- * State table loop detection. 
- * Detects if too many ( LE_STATE_PATIENCE_COUNT ) state changes occur without moving the glyph index 'g'.
- * 
- * Usage (pseudocode):
- *
- * {
- *   LE_STATE_PATIENCE_INIT();
- *
- *   int g=0; // the glyph index - expect it to be moving
- * 
- *   for(;;) {
- *     if(LE_STATE_PATIENCE_DECR()) { // decrements the patience counter
- *        // ran out of patience, get out.
- *        break;
- *     }
- *     
- *     LE_STATE_PATIENCE_CURR(int, g); // store the 'current'
- *     state = newState(state,g);
- *     g+= <something, could be zero>;
- *     LE_STATE_PATIENCE_INCR(g);  // if g has moved, increment the patience counter. Otherwise leave it.
- *   }
