 // Changed: 2007-08-06 by Alexander Kurochkin (inspector@list.ru)
-// Added: Decipher 4-bit mask.
-// Added: Chars Latin > 'L', Cyrilic, other symbols and special symbols for 
-//        simulation some latin and cyrilic chars.
-// Added: New Color schemas.
-// Deleted: Some minor bugs (StrokeNumber first parameter may be eq empty string, 
-//	false or null - added check see line 294;
-//	change color schema check for easy maintenance: 291;
-//	change check on key exist in chars array: moved from StrokeNumber 
-//	function to _GetLED: 251;
