Frame buffer manipulation.

MicroPython module: https://docs.micropython.org/en/v1.21.0/library/framebuf.html

This module provides a general frame buffer which can be used to create
bitmap images, which can then be sent to a display.

class FrameBuffer:
    """
    Construct a FrameBuffer object.  The parameters are:

        - *buffer* is an object with a buffer protocol which must be large
          enough to contain every pixel defined by the width, height and
          format of the FrameBuffer.
        - *width* is the width of the FrameBuffer in pixels
        - *height* is the height of the FrameBuffer in pixels
        - *format* specifies the type of pixel used in the FrameBuffer;
          permissible values are listed under Constants below. These set the
          number of bits used to encode a color value and the layout of these
          bits in *buffer*.
          Where a color value c is passed to a method, c is a small integer
          with an encoding that is dependent on the format of the FrameBuffer.
        - *stride* is the number of pixels between each horizontal line
          of pixels in the FrameBuffer. This defaults to *width* but may
          need adjustments when implementing a FrameBuffer within another
          larger FrameBuffer or screen. The *buffer* size must accommodate
          an increased step size.

    One must specify valid *buffer*, *width*, *height*, *format* and
    optionally *stride*.  Invalid *buffer* size or dimensions may lead to
    unexpected errors.

        ``array('h', [x0, y0, x1, y1, ... xn, yn])``.

        The optional *f* parameter can be set to ``True`` to fill the ellipse.

        The optional *m* parameter enables drawing to be restricted to certain
        quadrants of the ellipse. The LS four bits determine which quadrants are
        to be drawn, with bit 0 specifying Q1, b1 Q2, b2 Q3 and b3 Q4. Quadrants

        Draw another FrameBuffer on top of the current one at the given coordinates.
        If *key* is specified then it should be a color integer and the
        corresponding color will be considered transparent: all pixels with that
        color value will not be drawn. (If the *palette* is specified then the *key*
        is compared to the value from *palette*, not to the value directly from
        *fbuf*.)

        The *palette* argument enables blitting between FrameBuffers with differing
        formats. Typical usage is to render a monochrome or grayscale glyph/icon to
        a color display. The *palette* is a FrameBuffer instance whose format is
        that of the current FrameBuffer. The *palette* height is one pixel and its
        pixel width is the number of colors in the source FrameBuffer. The *palette*
        for an N-bit source needs 2**N pixels; the *palette* for a monochrome source
        would have 2 pixels representing background and foreground colors. The
        application assigns a color to each pixel in the *palette*. The color of the
        current pixel will be that of that *palette* pixel whose x position is the
        color of the corresponding source pixel.
