+  * A representation of the avatar portion of `ObjectCreateMessage` packet data.<br>
+  * <br>
+  * This object is huge, representing the quantity of densely-encoded data in its packet.
+  * Although the actual organization is ill-defined, the packet can be divided into seven parts.
+  * The first part maintains information about the avatar as a game object in the game environment.
+  * The second part maintains information as an ongoing representation of the avatar.
+  * This includes fixed details like name and gender, though it also includes mutable aspects like exosuit type.
+  * The third part maintains information about career in the game.
+  * The fourth part maintains miscellaneous status and pose information.
+  * The fifth part maintains part of the statistical information about participation in the game.
+  * The sixth part maintains a stream of typically zero'd unknown information.
+  * The seventh part maintains the inventory.
+  * The fifth and seventh parts can inflate the size of packet significantly due to their encoding.
+  * The fifth, in particular, is string data that can number in the hundreds of strings(!).<br>
+  * <br>
+  * Ignoring the strings, lists of strings, and the inventory, the base length of the packet is currently __1138__ bits.
+  * Some undefined bits in the packet can change the length of the packet by being set or unset.
+  * This will mess with the encoding and the decoding of later fields.
+  * Any data that is padded for byte-alignment will also have its padding adjusted.
+  * Each string adds either 8 or 16, plus an additional 8 or 16 per the number of characters.
+  * For the name, that's 16 per character, a minimum of two characters, plus the (current) padding.
+  * for the first time events and tutorials, that's 8 per character, plus the (current) padding of the first entry.
+  * For the first time events and tutorials, however, the size of the list is always a 32-bit number.
+  * The formal inventory entries are preceded by 1 absolute bit.<br>
+  * <br>
+  * The adjusted base length is therefore __1203__ bits (1138 + 32 + 32 + 1).
+  * Of that, __720__ bits are unknown.
+  * Including the values that are defaulted, __831__ bits are perfectly unknown.
