"""Set background image or return name of current backgroundimage.

Optional argument:

picname -- a string, name of a gif-file or "nopic".

If picname is a filename, set the corresponding image as background.

If picname is "nopic", delete backgroundimage, if present.

If picname is None, return the filename of the current backgroundimage.

Example (for a TurtleScreen instance named screen):

>>> screen.bgpic()

'nopic'

>>> screen.bgpic("landscape.gif")

>>> screen.bgpic()

'landscape.gif'
