// The Icon engine draws an ASCII format Icon to a MovieClip.
// Usage:
// _global.drawIcon(Icon,Target)
// _leve0.aMovieClip.drawIcon(Icon)
// 
// Please send feedback to ted@powersdk.com.
// Feedback, comments, and suggestions are welcome. ;)

//1.2 changes:
//   header support added
//   number CLUT mapping
//   icon shift via x & y header values or via drawIcon(icon, x, y)
//1.3 changes:
//   fixed issue with empty lines
