Notes about code structure of `old_cpp`

BZLIB - unchanged bzip2/libbzip2 version 1.0.6
CRYPTO - AES is in nasm assembler after recompile might work, SHA looks like pure c++ so after recompile might work (as encryption is not crucial at the moment I took only brief look into theese two.)
Controls.cpp - UI logic - borland dependent
Crc16.cpp - CRC-CCITT 16 bit Cyclic redundancy check - after removing win headers should work
Decoder.cpp - Nextdataprocessingstep The main decoding logic, after removing GUI stuff can be used
Ecc.cpp - Reed–Solomon error correction
Fileproc.cpp- Handling files + pages
Main.cpp highly borderland dependent - Updating buttons setting up windows
Printer.cpp - Printer UI + Drawing data into bitmap
Scanner.cpp - Scanner UI + Load Bitmap
Service.cpp - File related routines + Queue
