//|
//| :class:`PixelBuf` -- A fast RGB[W] pixel buffer for LED and similar devices
//| ===========================================================================
//|
//| :class:`~_pixelbuf.PixelBuf` implements an RGB[W] bytearray abstraction.
//|
//| .. class:: PixelBuf(size, buf, byteorder=BGR, brightness=0, rawbuf=None, offset=0, dotstar=False, auto_write=False, write_function=None, write_args=None)
//|
//|   Create a PixelBuf object of the specified size, byteorder, and bits per pixel.
//|
//|   When given a second bytearray (``rawbuf``), changing brightness adjusts the
//|   brightness of all members of ``buf``.
//|
//|   When only given ``buf``, ``brightness`` applies to the next pixel assignment.
//|
//|   When ``dotstar`` is True, and ``bpp`` is 4, the 4th value in a tuple/list
//|   is the individual pixel brightness (0-1).  Not compatible with RGBW Byteorders.
//|   Compatible `ByteOrder` classes are bpp=3, or bpp=4 and has_luminosity=True (g LBGR).
//|
//|   :param ~int size: Number of pixelsx
//|   :param ~bytearray buf: Bytearray to store pixel data in
//|   :param ~_pixelbuf.ByteOrder byteorder: Byte order constant from `_pixelbuf`
//|   :param ~float brightness: Brightness (0 to 1.0, default 1.0)
//|   :param ~bytearray rawbuf: Bytearray to store raw pixel colors in
//|   :param ~int offset: Offset from start of buffer (default 0)
//|   :param ~bool dotstar: Dotstar mode (default False)
//|   :param ~bool auto_write: Whether to automatically write pixels (Default False)
//|   :param ~callable write_function: (optional) Callable to use to send pixels
//|   :param ~list write_args: (optional) Tuple or list of args to pass to ``write_function``.  The
//|          PixelBuf instance is appended after these args.
