/*
 * Handle "target" and "look".

 * Note that this code can be called from "get_aim_dir()".
 *
 * All locations must be on the current panel.  Consider the use of
 * "panel_bounds()" to allow "off-panel" targets, perhaps by using
 * some form of "scrolling" the map around the cursor.  XXX XXX XXX
 * That is, consider the possibility of "auto-scrolling" the screen
 * while the cursor moves around.  This may require changes in the
 * "update_mon()" code to allow "visibility" even if off panel, and
 * may require dynamic recalculation of the "temp" grid set.
 *
 * Hack -- targeting/observing an "outer border grid" may induce
 * problems, so this is not currently allowed.
 *
 * The player can use the direction keys to move among "interesting"
 * grids in a heuristic manner, or the "space", "+", and "-" keys to
 * move through the "interesting" grids in a sequential manner, or
 * can enter "location" mode, and use the direction keys to move one
 * grid at a time in any direction.  The "t" (set target) command will
 * only target a monster (as opposed to a location) if the monster is
 * target_able and the "interesting" mode is being used.
 *
 * The current grid is described using the "look" method above, and
 * a new command may be entered at any time, but note that if the
 * "TARGET_LOOK" bit flag is set (or if we are in "location" mode,
 * where "space" has no obvious meaning) then "space" will scan
 * through the description of the current grid until done, instead
 * of immediately jumping to the next "interesting" grid.  This
 * allows the "target" command to retain its old semantics.
 *
 * The "*", "+", and "-" keys may always be used to jump immediately
 * to the next (or previous) interesting grid, in the proper mode.
 *
 * The "return" key may always be used to scan through a complete
 * grid description (forever).
 *
 * This command will cancel any old target, even if used from
 * inside the "look" command.
