/**
* This function takes a pointer to a grid info struct describing the
* contents of a grid location (as obtained through the function map_info)
* and fills in the character and attr pairs for display.
*
* ap and cp are filled with the attr/char pair for the monster, object or
* floor tile that is at the "top" of the grid (monsters covering objects,
* which cover floor, assuming all are present).
*
* tap and tcp are filled with the attr/char pair for the floor, regardless
* of what is on it. This can be used by graphical displays with
* transparency to place an object onto a floor tile, is desired.
*
* Any lighting effects are also applied to these pairs, clear monsters allow
* the underlying colour or feature to show through (ATTR_CLEAR and
* CHAR_CLEAR), multi-hued colour-changing (ATTR_MULTI) is applied, and so on.
* Technically, the flag "CHAR_MULTI" is supposed to indicate that a monster
* looks strange when examined, but this flag is currently ignored.
*
* NOTES:
* This is called pretty frequently, whenever a grid on the map display
* needs updating, so don't overcomplicate it.
*
* The "zero" entry in the feature/object/monster arrays are
* used to provide "special" attr/char codes, with "monster zero" being
* used for the player attr/char, "object zero" being used for the "pile"
* attr/char, and "feature zero" being used for the "darkness" attr/char.
*
* TODO:
* The transformations for tile colors, or brightness for the 16x16
* tiles should be handled differently. One possibility would be to
* extend feature_type with attr/char definitions for the different states.
* This will probably be done outside of the current text->graphics mappings
* though.
