Parameters
----------
`bgcolor` : tuple
Specify the background color as 4-tuple with values
between 0 and 1
`width` : int
Width of the window, in pixels. Defaults to 640, or the
screen width if `fullscreen` is True.
`height` : int
Height of the window, in pixels. Defaults to 480, or the
screen height if `fullscreen` is True.
`caption` : str or unicode
Initial caption (title) of the window. Defaults to
``sys.argv[0]``.
`fullscreen` : bool
If True, the window will cover the entire screen rather
than floating. Defaults to False.
`visible` : bool
Determines if the window is visible immediately after
creation. Defaults to True. Set this to False if you
would like to change attributes of the window before
having it appear to the user.
