0,0 → 1,6

Future: Allow several input arguments (e.g. *.ART)

Packer: Like the unpacker, implement a simulation mode (so that no ART file is written)

+ART FILES BY IMAGINATION PILOTS
+Technical overview by Daniel Marschall                                          15 Feb 2018
+                VERSION 1.x (16-bit era, "IPE16")
+                =================================
+Version 1.0     For game: "Blown Away" (1994)
+                * File signature "Art" + 20 NUL bytes
+                * Image names up to 23 characters
+                  (unsure if the 23th byte must be a zero terminator)
+                * LZW implementation: GIF standard implementation
+                  - variable code length between 9 and 12 bits
+                  - clear code (256)
+                  - end code (257)
+                * Pictures can only be 8-bit
+                * Each picture can either be LZW compressed (code "P")
+                  or uncompressed (code "p", lower case)
+                * Decompressed/raw data: Top-down pixel data
+                * Attached: Optional palette (R,G,B), uncompressed.
+                  (Sprites usually do not have a palette, so the game
+                   will use the palette of the parent picture)
+Version 1.1     For games: "Panic in the Park" (1995)
+                           "Where's Waldo? At the Circus" (1995)
+                * Codes for compression/raw are now "Q" and "q" instead of
+                  "P" and "p"
+                * Each picture has now a relative X- and Y-offsets for 'fine-tuning'.
+                  These offsets cannot be negative, though.
+                VERSION 2.x (32-bit era, "IPE32")
+                =================================
+Version 2.0     For games: "Where's Waldo? Exploring Geography" (1996)
+                           "Eraser Turnabout" (1997)
+                           "Virtual K'Nex" (1998)
+                * File signature "ART_DATA"
+                * Image names up to 8 characters;
+                  no zero termination required after the 8 characters.
+                * LZW implementation by Mark R. Nelson and Shawn M. Regan
+                  - variable code length between 9 and 13 bits
+                  - clear code (256)
+                  - end code (257)
+                * Pictures are divided into chunks. Each chunk can be compressed or
+                  uncompressed. Limitations:
+                  - Each compressed chunk (except the last one) must decode into
+                    exactly 16382 (0x3FFE) bytes of uncompressed data.
+                  - The size of the compressed data of a chunk must not exceed the
+                    size of the original uncompressed data.
+                * The size of each chunk (raw or compressed) is limited
+                  to max. 32767 Bytes (0x7FFF).
+                * Decompressed/raw data: Windows Bitmap (without file header);
+                  therefore, theoretically every color depth/compression/etc. can be used.
+                  For 8-bit pictures, the palette is included in the Bitmap.
+                * Re-using of parent palette is not possible.
