//               see/update also COLCODE.INC for assembly

// for transparent code repeated for 1 to UNIQUE_REPEAT_CODE_NUM times,
// write FEW_TRANSPARENT_CODE(repeated_times)
// for transparent code repeated for UNIQUE_REPEAT_CODE_NUM+1 to 255 times,
// write two bytes, MANY_TRANSPARENT_CODE and repeated_times
