/**
 * Quake 1 model format is used to store 3D models completely with
 * textures and animations used in the game. Quake 1 engine
 * (retroactively named "idtech2") is a popular 3D engine first used
 * for Quake game by id Software in 1996.
 * 
 * Model is constructed traditionally from vertices in 3D space, faces
 * which connect vertices, textures ("skins", i.e. 2D bitmaps) and
 * texture UV mapping information. As opposed to more modern,
 * bones-based animation formats, Quake model was animated by changing
 * locations of all vertices it included in 3D space, frame by frame.
 * 
 * File format stores:
 * 
 * * "Skins" — effectively 2D bitmaps which will be used as a
 *   texture. Every model can have multiple skins — e.g. these can be
 *   switched to depict various levels of damage to the
 *   monsters. Bitmaps are 8-bit-per-pixel, indexed in global Quake
 *   palette, subject to lighting and gamma adjustment when rendering
 *   in the game using colormap technique.
 * * "Texture coordinates" — UV coordinates, mapping 3D vertices to
 *   skin coordinates.
 * * "Triangles" — triangular faces connecting 3D vertices.
 * * "Frames" — locations of vertices in 3D space; can include more
 *   than one frame, thus allowing representation of different frames
 *   for animation purposes.
 * 
 * Originally, 3D geometry for models for Quake was designed in [Alias
 * PowerAnimator](https://en.wikipedia.org/wiki/PowerAnimator),
 * precursor of modern day Autodesk Maya and Autodesk Alias. Therefore,
 * 3D-related part of Quake model format followed closely Alias TRI
 * format, and Quake development utilities included a converter from Alias
 * TRI (`modelgen`).
 * 
 * Skins (textures) where prepared as LBM bitmaps with the help from
 * `texmap` utility in the same development utilities toolkit.
