Jill of the Jungle is done by double buffering, that is, the pages are flipped
between 1 and 2 to achieve the effect.  There is no such thing as a static
window to scroll in using the IBM Graphics cards.  This technique exists on the
Amiga, though.

All Tim Sweeney did was replot the whole map each time (the current view). 
That's all there was to it.
