.PIC: Images and other stuff
    Begins with header with info on all contained files. Last header entry is blank (all zeros):
        4 bytes - Offset to file
        2 bytes - Type:
            0x0300 == closed book or runes,
            0x0500 == navigation images and items,
            0x1300 == note, open book, spell casting interface, or frame around embedded video,
            0x1500 == big static image,
            0x4501 == some kind of overlay images to big images,
        3*2 bytes - Type specific data/arguments
            For images, first and second argument specifies width and height.
        4 bytes - Offset to next file
        ...
    Type 0x1300 and 0x1500 begins with a 256*3 RGB palette in 6 bit BGR format (at the offset), followed by the image itself.
    Type 0x4501 begins with 2*2 byte header, might be coordinates on where to overlay. Palette unknown.
    Type 0x500 has no header. Palette unknown.
    DGATE000-19.PIC == Static images of places and static overlays
    DGATE020-28.PIC == books
    DGATE040.PIC    == Static full size images
    DGATE050-58.PIC == Animations
    DGATE060-61.PIC == Spells, runes, etc.
    DGATE062-63.PIC == Pipes and pipe animations
    DGATE064.PIC    == Dwarven cave puzzle
    DGATE066.PIC    == End puzzle
    DGATE067.PIC    == Book flip page animation
    DGATE068.PIC    == Clock puzzle
    DGATE069.PIC    == Steering stone
    DGATE070.PIC    == Labyrinth on Abarrach (world of stone)
    DGATE071.PIC    == Images in credits
    DGATE075-78.PIC == World map and ship animations
    DGATE080-86.PIC == Images shown when talking to a person

.Q: Animations. Might be divided in sections with MF and MZ as delimiters. MF is followed by a new offset in the same file, MZ is probably followed by a size or a relative offset.
    .Q files from the dgatevga folder of the CD can be played back with xanim (FLI format).

.MUS: Music. XMIDI format.
    Begins with header (of course). First 16 bits are number of songs/melodies + 1 (don't really know why +1).
    Rest of header consists of offset (uint32_t) and size (uint16_t) pairs.

.VOC: Voices. 8bit, 2 channels (stereo), somewhere around 10900 Hz (aplay -c2 -r10900 DGATE001.VOC)
    Begins with a header. First 16 bits are number of sounds +1 (again, don't really know why +1)
    Rest of header consists of offsets (uint32_t) to each sound.

.FLI: Animation. Books for example
