 **
 *i  DIGUY_AGENT_BEHAVIOR_NONE
 **
 **      Agent functionality is completely inactive.  The character's actions
 **      are determined by its character path or direct DI-Guy API calls.
 **
 *i  DIGUY_AGENT_BEHAVIOR_TRAVEL
 **
 **      Agent attempts to travel close to a path shape.  Many agents can use
 **      the same path shape for the travel behavior.
 **
 *i  DIGUY_AGENT_BEHAVIOR_PATH_FOLLOW
 **
 **      Similar to DIGUY_AGENT_BEHAVIOR_TRAVEL, but agent follows a
 **      character path instead of a path shape, and attempts to match the
 **      timing of the character path in addition to the path shape.  If the
 **      agent is interrupted from the path, it will attempt to resume it
 **      where it left off.
 **
 *i  DIGUY_AGENT_BEHAVIOR_WANDER
 **
 **      Agent wanders a region.  In this case wander means it will select a
 **      random point within the region and move close to it, and then wait
 **      there for a period of time before selecting a new point in the
 **      region.
 **
 *i  DIGUY_AGENT_BEHAVIOR_MINGLE
 **
 **      Similar to wander, but agents attempt to move together to various
 **      places in the region.
 **
 *i  DIGUY_AGENT_BEHAVIOR_FLEE
 **
 **      Agent attempts to move away from a specified character or point.
 **
 *i  DIGUY_AGENT_BEHAVIOR_PURSUE
 **
 **      Agent attempts to stay close to a specified character or member of a
 **      group.
 **
 *i  DIGUY_AGENT_BEHAVIOR_ATTACK
 **
 **      Similar to pursue, but once agents are close enough they will attack
 **      the target.
 **
 *i  DIGUY_AGENT_BEHAVIOR_IDLE
 **

 **
 **    DI-Guy agent untrap methods.
 **
 **      Following is a short description of each untrap method.  See the
 **      DI-Guy AI documentation for more details.
 **
 *i    DIGUY_AGENT_UNTRAP_METHOD_NONE
 **
 **      The agent makes no attempt to become untrapped.  This can result in
 **      the agent blindly walking into a wall until its desired position
 **      changes.
 **
 *i    DIGUY_AGENT_UNTRAP_METHOD_NAV_PATH
 **
 **      The agent will try to create a nav path in its current region to its
 **      desired position.  If the desired position is not inside the region,
 **      a valid nav path may not be able to be found.
 **
 *i    DIGUY_AGENT_UNTRAP_METHOD_RANDOM_TURN
 **
 **      The agent will stop moving and turn a random amount.  This minor
 **      course change can sometimes move a character around a small
 **      obstacle.
 **
 *i    DIGUY_AGENT_UNTRAP_METHOD_GHOST
 **
 **      Agent feelers will stop having an effect for a short time.  This
 **      allows the agent to walk through a wall toward its desired
 **      position.
 **
 *i    DIGUY_AGENT_UNTRAP_METHOD_TELEPORT
 **
 **      This is an extreme method, typically used as a last resort.  The
 **      agent abruptly teleports to its desired position.
 **
 *i    DIGUY_AGENT_UNTRAP_METHOD_STOP_MOVING
 **
 **      Somewhat similar to DIGUY_AGENT_UNTRAP_METHOD_NONE, but the current
 **      behavior of the agent is set to none, and the agent character's
 **      desired position is set to its current position.

 **
 **      Painting will add area to the current subregion.  This may end up
 **      adding area to the base subregion, as well, as it contains at
 **      least the areas of all subregions.
 **
 *i    DIGUY_REGION_PAINTBRUSH_MODE_ERASE
 **
 **      Painting will remove area from the current subregion.  If the base
 **      subregion is erased, all matching areas in other subregions will be
 **      erased, as well.
 **
 *i    DIGUY_REGION_PAINTBRUSH_MODE_UNGROUND_CLAMP
 **
 **      Painting will remove area from the current subregion, will also remove 
 **      the height value from the region and the next time the area is painted 
 **      it will adopt the height values of the new paint command.
 **
 *i    DIGUY_REGION_PAINTBRUSH_MODE_MOVE_MESH
 **
 **      Moves the mesh to a new location in space and re-ground clamps
 **
 *i    DIGUY_REGION_PAINTBRUSH_MODE_REACHABLE
 **
 **      Painting reachable will indicate that this is a spot the path planner 
 **      should be willing to traverse. Erasing Reachable colors the spot black 
 **      and indicates that it's not crossable or paint-able.

 *b  Description:
 **
 **    DI-Guy subregions.
 **
 **    Regions are irregularly shaped areas in the scene that can be used
 **    in a number of ways.
 **
 **    Regions contain a number of subregions.  Each subregion is represented
 **    by a different color, and most often the subregions are referred to
 **    by their color.  Subregions are not mutually exclusive; a point in
 **    the scene may be in all of the base, populate, and green subregions,
 **    for example.
 **
 **    Many functions that take one subregion as an argument use the string
 **    name of the subregion.
 **
 **    Functions that can have multiple subregions specified use a subregion
 **    mask made up of diguySubregionMask values that can be or'ed together
 **    to indicate multiple valid subregions.  See diguySubregionMask for
 **    more information.
 **
 *i    DIGUY_SUBREGION_BASE
 **
 **      This subregion is really a "super-region", in that its bounds contain
 **      all of the other subregions, and possibly more.
 **
 **      If any subregion of a top-level region is expanded beyond the bounds
 **      of the base subregion, the base subregion will be expanded until
 **      it encompasses the expansion.
 **
 **      If, however, a non-base subregion is subsequently shrunk, the base
 **      subregion will not shrink.
 **
 **      If the base subregion is shrunk, any portion of each non-base
 **      subregion that is no longer in the base subregion will be removed.
 **
 *i    DIGUY_SUBREGION_POPULATE
 **
 **      The subregion into which new crowd agents will be placed if the
 **      region is populated or repopulated.  This subregion is typically
 **      purple.
 **
 **    DIGUY_SUBREGION_[color]
 **
 **      The "color" subregions are free to be used in any way a scenario
 **      designer wants.  Their colors are based on their name.
 **
 *i    DIGUY_SUBREGION_ROAD
 **
 **      Road subregions are commonly used as preferred subregions for vehicle
 **      travel, and repulsion subregions for human travel.  This subregion
 **      is typically gray.
 **
 *i    DIGUY_SUBREGION_SIDEWALK
 **
 **      Sidewalk subregions are commonly used as preferred subregions for
 **      human travel, and repulsion subregions for vehicles.  This subregion
 **      is typically white.
 **
 *i    DIGUY_SUBREGION_CROSSWALK
 **
 **      Humans will tend to prefer crosswalk subregions over road subregions,
 **      but prefer sidewalk subregions over crosswalk subregions.  This
 **      subregion is typically a light yellow.
