 *  When any of these tags are used, the tag will override default Top/Middle/Bottom
 *
 *  Use tags \[top] \[middle] \[bottom] on the same line to show text at the same time.
 * \[bottom]Hello, how are you doing?\[top]¿Hola cómo estás?
 *  
 * Optional tag parameters (only needed on first line) (must be in this order)
 *  
 * \[pos hue:R,G,B] \[top face:FaceName,Index,HueRotate] face hueRotate is optional 
 *
 * example \[middle hue:155,0,250 face:People4,2,150]
