// Map Marker --------------------------------------------------------------
//
// This class uses the following argument:
//   args[0] == 0, shows the sprite at this actor
//           != 0, shows the sprite for all actors whose TIDs match instead
//
//   args[1] == 0, show the sprite always
//           == 1, show the sprite only after its sector has been drawn
//
// To enable display of the sprite, activate it. To turn off the sprite,
// deactivate it.
//
// All the code to display it is in am_map.cpp.
//
