'scrlptch.zip' contains two files: 'scrl282.dif' and 'scrl283.dif',
for Angband 2.8.2 and 2.8.3, respectively. Earlier versions require
extensive (and incompatible) modifications to allow arbitrary
positioning of the map panel, so the patch is inapplicable to these.

The patches add offscreen targetting, continuous updating of the map
panel, and modifications which allow the Borg to use the recentering.

The files patched are 'borg8.c', 'cave.c', 'cmd3.c', 'defines.h',
'tables.c', and 'xtra2.c'.  Apply the patch using the '-F5' and '-l'
options.  'scrl282.dif' does not include the 'borg8.c' modifications
because version 2.8.2 did not have a Borg; and does not include the
'tables.c' modifications because 'diff' dies for no understandable
reason while reading the file :-/  The necessary changes are simple;
look at the appropriate section of 'scrl283.dif'.

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.
