------------------------------------------------------------------------------
 ** Description
 
 This script allows you to take a full image of any of your game's maps
 and export. An image of the map is referred to as a "mapshot" (as opposed to
 screenshot).
 
 The script provides various configuration options to control what kinds of
 things you want to see on your map, such as events, vehicles, region ID's, or
 specific tile properties.
 
------------------------------------------------------------------------------
 ** Usage
 
 The default key for taking a mapshot is F7. This can be changed in the
 configuration section.
 
 To take a mapshot, first start the game, and then hit F7.
 A message will appear informing you that a mapshot was successfully taken.
 
 Alternatively, you can use script calls to take mapshots.
 
    Map_Saver.new(map_id).export
 
 Aside from exporting images, you are able to use the image that the
 map saver captures.
 
   ms = Map_Saver.new(map_id)
   bmp = ms.map_image
 
 This gives you a reference to a Bitmap object that contains an image of
 your map.
