4// Description: Module to generate Dotted LED-like digits

10// Changed: 2007-08-06 by Alexander Kurochkin (inspector@list.ru)
11// Added: Decipher 4-bit mask.
12// Added: Chars Latin > 'L', Cyrilic, other symbols and special symbols for
13// simulation some latin and cyrilic chars.
14// Added: New Color schemas.
15// Deleted: Some minor bugs (StrokeNumber first parameter may be eq empty string,
16// false or null - added check see line 294;
17// change color schema check for easy maintenance: 291;
18// change check on key exist in chars array: moved from StrokeNumber
19// function to _GetLED: 251;
20//
21//========================================================================

23// Samples for troubled chars: "Ô¡ Ø\r Ù\r Û| ÞÎ Ì\r >\n< W\r"
24// Ô Ø Ù Û Þ Ì Æ W

27// Each character is encoded line by line with the "On"-LEDs corresponding to
28// a '1' in the bianry mask of 4 bits.
