Generator function which yields a series of frames depicting *text*
scrolling in *direction* across the display. Each frame will be a
:class:`~PIL.Image.Image` 8x8 pixels in size.
The *text*, *font*, *size*, *foreground*, and *background* parameters are
all equivalent to those in :func:`draw_text` (which is called to handle
rendering the text).
The *direction* parameter defaults to 'left' which results in the text
scrolling from the right-hand side of the display towards the left (the
typical direction for left-to-right languages). The value 'right' can also
be specified to reverse the scrolling direction.
The *duration* and *fps* parameters control how many frames will be yielded
by the function. The *duration* parameter measures the length of the
animation in seconds, while *fps* controls how many frames should be shown
per second. Hence, if *duration* is 2 and *fps* is 15, the
generator will yield 30 frames.
The default for *duration* is ``None`` indicating that the function should
determine the duration based on the length of the rendered text (in this
case *fps* is ignored). In this case the generator will produce frames
which scroll 1 pixel horizontally per frame.
The resulting animation will start with a full frame of *background* color;
the text will appear to scroll onto the display, and off again with the
final frame guaranteed to be another full frame of *background* color.
