    A Windows bitmap with the given mode and size.  The mode can be one of "1",
    "L", "P", or "RGB".

    If the display requires a palette, this constructor creates a suitable
    palette and associates it with the image. For an "L" image, 128 greylevels
    are allocated. For an "RGB" image, a 6x6x6 colour cube is used, together
    with 20 greylevels.

    To make sure that palettes work properly under Windows, you must call the
    ``palette`` method upon certain events from Windows.

    :param image: Either a PIL image, or a mode string. If a mode string is
                  used, a size must also be given.  The mode can be one of "1",
                  "L", "P", or "RGB".
    :param size: If the first argument is a mode string, this
                 defines the size of the image.

        :param handle: Device context (HDC), cast to a Python integer, or an
                       HDC or HWND instance.  In PythonWin, you can use
                       ``CDC.GetHandleAttrib()`` to get a suitable handle.

        Same as expose, but allows you to specify where to draw the image, and
        what part of it to draw.

        The destination and source areas are given as 4-tuple rectangles. If
        the source is omitted, the entire image is copied. If the source and
        the destination have different sizes, the image is resized as
        necessary.

        Installs the palette associated with the image in the given device
        context.

        This method should be called upon **QUERYNEWPALETTE** and
        **PALETTECHANGED** events from Windows. If this method returns a
        non-zero value, one or more display palette entries were changed, and
        the image should be redrawn.

        :param handle: Device context (HDC), cast to a Python integer, or an
                       HDC or HWND instance.
        :return: A true value if one or more entries were changed (this
                 indicates that the image should be redrawn).

        :param im: A PIL image.  The size must match the target region.
                   If the mode does not match, the image is converted to the
                   mode of the bitmap image.
