/*
 * Build a string describing a monster in some way.
 *
 * We can correctly describe monsters based on their visibility.
 * We can force all monsters to be treated as visible or invisible.
 * We can build nominatives, objectives, possessives, or reflexives.
 * We can selectively pronominalize hidden, visible, or all monsters.
 * We can use definite or indefinite descriptions for hidden monsters.
 * We can use definite or indefinite descriptions for visible monsters.
 *
 * Pronominalization involves the gender whenever possible and allowed,
 * so that by cleverly requesting pronominalization / visibility, you
 * can get messages like "You hit someone.  She screams in agony!".
 *
 * Reflexives are acquired by requesting Objective plus Possessive.
 *
 * If no m_ptr arg is given (?), the monster is assumed to be hidden,
 * unless the "Assume Visible" mode is requested.
 *
 * If no r_ptr arg is given, it is extracted from m_ptr and r_info
 * If neither m_ptr nor r_ptr is given, the monster is assumed to
 * be neuter, singular, and hidden (unless "Assume Visible" is set),
 * in which case you may be in trouble... :-)
 *
 * I am assuming that no monster name is more than 70 characters long,
 * so that "char desc[80];" is sufficiently large for any result.
 *
 * Mode Flags:
 *   0x01 --> Objective (or Reflexive)
 *   0x02 --> Possessive (or Reflexive)
 *   0x04 --> Use indefinites for hidden monsters ("something")
 *   0x08 --> Use indefinites for visible monsters ("a kobold")
 *   0x10 --> Pronominalize hidden monsters
 *   0x20 --> Pronominalize visible monsters
 *   0x40 --> Assume the monster is hidden
 *   0x80 --> Assume the monster is visible
 *
 * Useful Modes:
 *   0x00 --> Full nominative name ("the kobold") or "it"
 *   0x04 --> Full nominative name ("the kobold") or "something"
 *   0x80 --> Genocide resistance name ("the kobold")
 *   0x88 --> Killing name ("a kobold")
 *   0x22 --> Possessive, genderized if visable ("his") or "its"
 *   0x23 --> Reflexive, genderized if visable ("himself") or "itself"

/*
 * This function updates the monster record of the given monster
 *
 * This involves extracting the distance to the player (if requested),
 * and then checking for visibility (natural, infravision, see-invis,
 * telepathy), updating the monster visibility flag, redrawing (or
 * erasing) the monster when its visibility changes, and taking note
 * of any interesting monster flags (cold-blooded, invisible, etc).
 *
 * Note the new "mflag" field which encodes several monster state flags,
 * including "view" for when the monster is currently in line of sight,
 * and "mark" for when the monster is currently visible via detection.
 *
 * The only monster fields that are changed here are "cdis" (the
 * distance from the player), "ml" (visible to the player), and
 * "mflag" (to maintain the "MFLAG_VIEW" flag).
 *
 * Note the special "update_monsters()" function which can be used to
 * call this function once for every monster.
 *
 * Note the "full" flag which requests that the "cdis" field be updated,
 * this is only needed when the monster (or the player) has moved.
 *
 * Every time a monster moves, we must call this function for that
 * monster, and update the distance, and the visibility.  Every time
 * the player moves, we must call this function for every monster, and
 * update the distance, and the visibility.  Whenever the player "state"
 * changes in certain ways ("blindness", "infravision", "telepathy",
 * and "see invisible"), we must call this function for every monster,
 * and update the visibility.
 *
 * Routines that change the "illumination" of a grid must also call this
 * function for any monster in that grid, since the "visibility" of some
 * monsters may be based on the illumination of their grid.
 *
 * Note that this function is called once per monster every time the
 * player moves.  When the player is running, this function is one
 * of the primary bottlenecks, along with "update_view()" and the
 * "process_monsters()" code, so efficiency is important.
 *
 * Note the optimized "inline" version of the "distance()" function.
 *
 * A monster is "visible" to the player if (1) it has been detected
 * by the player, (2) it is close to the player and the player has
 * telepathy, or (3) it is close to the player, and in line of sight
 * of the player, and it is "illuminated" by some combination of
 * infravision, torch light, or permanent light (invisible monsters
 * are only affected by "light" if the player can see invisible).
 *
 * Monsters which are not on the current panel may be "visible" to
 * the player, and their descriptions will include an "offscreen"
 * reference.  Currently, offscreen monsters cannot be targetted
 * or viewed directly, but old targets will remain set.  XXX XXX
 *
 * The player can choose to be disturbed by several things, including
 * "disturb_move" (monster which is viewable moves in some way), and
 * "disturb_near" (monster which is "easily" viewable moves in some
 * way).  Note that "moves" includes "appears" and "disappears".
