//|
//| :class:`Display` -- Manage updating a display over a display bus
//| ==========================================================================
//|
//| This initializes a display and connects it into CircuitPython. Unlike other
//| objects in CircuitPython, Display objects live until `displayio.release_displays()`
//| is called. This is done so that CircuitPython can use the display itself.
//|
//| Most people should not use this class directly. Use a specific display driver instead that will
//| contain the initialization sequence at minimum.
//|
//| .. class:: Display(display_bus, init_sequence, *, width, height, colstart=0, rowstart=0, rotation=0, color_depth=16, grayscale=False, pixels_in_byte_share_row=True, set_column_command=0x2a, set_row_command=0x2b, write_ram_command=0x2c, set_vertical_scroll=0, backlight_pin=None, brightness_command=None, brightness=1.0, auto_brightness=False, single_byte_bounds=False, data_as_commands=False)
//|
//| Create a Display object on the given display bus (`displayio.FourWire` or `displayio.ParallelBus`).
//|
//| The ``init_sequence`` is bitpacked to minimize the ram impact. Every command begins with a
//| command byte followed by a byte to determine the parameter count and if a delay is need after.
//| When the top bit of the second byte is 1, the next byte will be the delay time in milliseconds.
//| The remaining 7 bits are the parameter count excluding any delay byte. The third through final
//| bytes are the remaining command parameters. The next byte will begin a new command definition.
//| Here is a portion of ILI9341 init code:
//|
//| .. code-block:: python
//|
//| init_sequence = (b"\xe1\x0f\x00\x0E\x14\x03\x11\x07\x31\xC1\x48\x08\x0F\x0C\x31\x36\x0F" # Set Gamma
//| b"\x11\x80\x78"# Exit Sleep then delay 0x78 (120ms)
//| b"\x29\x80\x78"# Display on then delay 0x78 (120ms)
//| )
//| display = displayio.Display(display_bus, init_sequence, width=320, height=240)
//|
//| The first command is 0xe1 with 15 (0xf) parameters following. The second and third are 0x11 and
//| 0x29 respectively with delays (0x80) of 120ms (0x78) and no parameters. Multiple byte literals
//| (b"") are merged together on load. The parens are needed to allow byte literals on subsequent
//| lines.
//|
//| The initialization sequence should always leave the display memory access inline with the scan
//| of the display to minimize tearing artifacts.
//|
//| :param display_bus: The bus that the display is connected to
//| :type display_bus: displayio.FourWire or displayio.ParallelBus
//| :param buffer init_sequence: Byte-packed initialization sequence.
//| :param int width: Width in pixels
//| :param int height: Height in pixels
//| :param int colstart: The index if the first visible column
//| :param int rowstart: The index if the first visible row
//| :param int rotation: The rotation of the display in degrees clockwise. Must be in 90 degree increments (0, 90, 180, 270)
//| :param int color_depth: The number of bits of color per pixel transmitted. (Some displays
//| support 18 bit but 16 is easier to transmit. The last bit is extrapolated.)
//| :param bool grayscale: True if the display only shows a single color.
//| :param bool pixels_in_byte_share_row: True when pixels are less than a byte and a byte includes pixels from the same row of the display. When False, pixels share a column.
//| :param int set_column_command: Command used to set the start and end columns to update
//| :param int set_row_command: Command used so set the start and end rows to update
//| :param int write_ram_command: Command used to write pixels values into the update region. Ignored if data_as_commands is set.
//| :param int set_vertical_scroll: Command used to set the first row to show
//| :param microcontroller.Pin backlight_pin: Pin connected to the display's backlight
//| :param int brightness_command: Command to set display brightness. Usually available in OLED controllers.
//| :param bool brightness: Initial display brightness. This value is ignored if auto_brightness is True.
//| :param bool auto_brightness: If True, brightness is controlled via an ambient light sensor or other mechanism.
//| :param bool single_byte_bounds: Display column and row commands use single bytes
//| :param bool data_as_commands: Treat all init and boundary data as SPI commands. Certain displays require this.
