//| :class:`FramebufferDisplay` -- Manage updating a display with framebuffer in RAM
//| ================================================================================
//|
//| 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.
//|
//| .. class:: FramebufferDisplay(framebuffer, *, width, height, colstart=0, rowstart=0, rotation=0, color_depth=16, grayscale=False, pixels_in_byte_share_row=True, bytes_per_cell=1, reverse_pixels_in_byte=False, backlight_pin=None, brightness=1.0, auto_brightness=False, auto_refresh=True, native_frames_per_second=60)
//|
//|   Create a Display object with the given framebuffer (a buffer, array, ulab.array, etc)
//|
//|   :param framebuffer: The framebuffer that the display is connected to
//|   :type framebuffer: any core object implementing the framebuffer protocol
//|   :param int width: Width in pixels
//|   :param int height: Height in pixels
//|   :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 int bytes_per_cell: Number of bytes per addressable memory location when color_depth < 8. When greater than one, bytes share a row or column according to pixels_in_byte_share_row.
//|   :param microcontroller.Pin backlight_pin: Pin connected to the display's backlight
//|   :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 auto_refresh: Automatically refresh the screen
//|   :param int native_frames_per_second: Number of display refreshes per second
