This reader is based on the specification available from:
https://www.flipcode.com/archives/Quake_2_BSP_File_Format.shtml
and has been tested with a few sample files found using google.

.. note::
    This format cannot be automatically recognized, so the reader
    is not registered for use with :py:func:`PIL.Image.open()`.
    To open a WAL file, use the :py:func:`PIL.WalImageFile.open()` function instead.

    Load texture from a Quake2 WAL texture file.

    By default, a Quake2 standard palette is attached to the texture.
    To override the palette, use the :py:func:`PIL.Image.Image.putpalette()` method.

    :param filename: WAL file name, or an opened file handle.
    :returns: An image instance.
