'scrolling-patch.zip' contains nine files, which add offscreen 
targetting, continuous updating of the map panel, and modifications 
which allow the Borg to use the recentering.

Files labeled 'bugfix' are patches for versions of Angband patched
with the previous scrolling patch; those labeled 'full' patch the
original source code.  The two files labelled 'Z' are patches for
Zangband source.  'scroll-Z-226c-full.dif' patches Zangband 
version 2.26c; 'scroll-Z-a226c-bugfix.dif' patches the recent release
called 'Zangband a226c', by Prfnoff.

I'd like to thank Ben Harrison for discovering that the previous
version was buggy, allowing me to fix it; and also Prfnoff, as his
adaptation of my scrolling patch to Zangband was vital to the
patches for Angband 2.8.0 and 2.8.1, and the patches for Zangband.

The offscreen targetting works normally while on the current screen.
Once the edge of the screen is reached, it will find the nearest
'interesting' grid (ie, one containing a visible monster) in the
direction given, and skip to the map panel containing it.  If no
interesting grid can be found, it will switch to 'offset' mode,
allowing any grid to be targetted.  'l'ook and e'x'amine operate
similarly but, as normal, will also consider objects and certain
features 'interesting'.  Note that 'expand_look' must be true in
order to examine grids not in line-of-sight.
