Chapter - The map-display window kind
[We need to change Glimmr Canvas-Based Drawing's basic window-drawing behavior for the automap window. One of the most straightforward ways to do this is with a kind. A property would work as well, but we don't really want to be able to change this during play--map display would break entirely.]
A map-display window is a kind of graphlink g-window.
The map viewport is a g-window that varies. [If the author doesn't explicitly name the map viewport, we will automatically select a map-display window to be the viewport when play begins. In most cases, this will be the only existing map-display window.]
[The author may provide a maximum map size to use. This refers to the number of *tiles* to be displayed, not the maximum number of pixels, and can be used to restrict the size of the map for either performance or aesthetic reasons. For example, a fixed map size combined with a restricted number of available zoom levels can make it easier to predict the output size of the map.]
A map-display window has a number called the maximum map width. The maximum map width of a map-display window is usually 0.
A map-display window has a number called the maximum map height. The maximum map height of a map-display window is usually 0.
