An interactive application or animation should call this once
per frame to have th display contents updated on the terminal.
It can optionally update just a part of the output screen, if
pos1 or pos2 are given.
As of pre-0.4.0 development an app should manually provide
its "mainloop" and call this on each frame. Later development
will probably have an optional higher level loop
that will automate calling here.
Args:
- pos1, pos2: Corners of a rectangle delimitting the area to be updated.
(optionally, 'pos1' can be a Rect object)
