/**
* This function takes a grid location (x, y) and extracts information the

* passed in 'g'.
*
* The information filled in is as follows:
* - g->f_idx is filled in with the terrain's feature type, or FEAT_NONE
* if the player doesn't know anything about the grid. The function
* makes use of the "mimic" field in terrain in order to allow one
* feature to look like another (hiding secret doors, invisible traps,
* etc). This will return the terrain type the player "Knows" about,
* not necessarily the real terrain.
* - g->m_idx is set to the monster index, or 0 if there is none (or the
* player doesn't know it).
* - g->first_kind is set to the object_kind of the first object in a grid
* that the player knows about, or NULL for no objects.
* - g->muliple_objects is true if there is more than one object in the
* grid that the player knows and cares about (to facilitate any special
* floor stack symbol that might be used).
* - g->in_view is true if the player can currently see the grid - this can
* be used to indicate field-of-view, such as through the
* OPT(player, view_bright_light) option.
* - g->lighting is set to indicate the lighting level for the grid:
* LIGHTING_DARK for unlit grids, LIGHTING_LIT for inherently light
* grids (lit rooms, etc), LIGHTING_TORCH for grids lit by the player's
* light source, and LIGHTING_LOS for grids in the player's line of sight.
* Note that lighting is always LIGHTING_LIT for known "interesting" grids
* like walls.
* - g->is_player is true if the player is on the given grid.
* - g->hallucinate is true if the player is hallucinating something "strange"
* for this grid - this should pick a random monster to show if the m_idx
* is non-zero, and a random object if first_kind is non-zero.
*
* NOTES:
* This is called pretty frequently, whenever a grid on the map display
* needs updating, so don't overcomplicate it.
*
* Terrain is remembered separately from objects and monsters, so can be
* shown even when the player can't "see" it. This leads to things like
* doors out of the player's view still change from closed to open and so on.
*
* TODO:
* Hallucination is currently disabled (it was a display-level hack before,
* and we need it to be a knowledge-level hack). The idea is that objects
* may turn into different objects, monsters into different monsters, and
* terrain may be objects, monsters, or stay the same.

/**
* This function takes a grid location (x, y) and extracts information the
* player is allowed to know about it, filling in the grid_data structure
* passed in 'g'.
*
* The information filled in is as follows:
* - g->f_idx is filled in with the terrain's feature type, or FEAT_NONE
* if the player doesn't know anything about the grid. The function
* makes use of the "mimic" field in terrain in order to allow one
* feature to look like another (hiding secret doors, invisible traps,
* etc). This will return the terrain type the player "Knows" about,
* not necessarily the real terrain.
* - g->m_idx is set to the monster index, or 0 if there is none (or the
* player doesn't know it).
* - g->first_kind is set to the object_kind of the first object in a grid
* that the player knows about, or NULL for no objects.
* - g->muliple_objects is TRUE if there is more than one object in the
* grid that the player knows and cares about (to facilitate any special
* floor stack symbol that might be used).
* - g->in_view is TRUE if the player can currently see the grid - this can
* be used to indicate field-of-view, such as through the OPT(view_bright_light)
* option.
* - g->lighting is set to indicate the lighting level for the grid:
* LIGHTING_DARK for unlit grids, LIGHTING_LIT for inherently light
* grids (lit rooms, etc), LIGHTING_TORCH for grids lit by the player's
* light source, and LIGHTING_LOS for grids in the player's line of sight.
* Note that lighting is always LIGHTING_LIT for known "interesting" grids
* like walls.
* - g->is_player is TRUE if the player is on the given grid.
* - g->hallucinate is TRUE if the player is hallucinating something "strange"
* for this grid - this should pick a random monster to show if the m_idx
* is non-zero, and a random object if first_kind is non-zero.
*
* NOTES:
* This is called pretty frequently, whenever a grid on the map display
* needs updating, so don't overcomplicate it.
*
* Terrain is remembered separately from objects and monsters, so can be
* shown even when the player can't "see" it. This leads to things like
* doors out of the player's view still change from closed to open and so on.
*
* TODO:
* Hallucination is currently disabled (it was a display-level hack before,
* and we need it to be a knowledge-level hack). The idea is that objects
* may turn into different objects, monsters into different monsters, and
* terrain may be objects, monsters, or stay the same.

*
* Hack -- targetting/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.
*
*
* 'mode' is one of TARGET_LOOK or TARGET_KILL.
