Is there a standard Aqua way to handle a practically infinite document?

For example, imagine a level editor for a tile-based game. The level has no preset size (though it's technically limited by NSInteger's size); tiles can be placed anywhere on the grid. Is there a standard interface for scrolling through such a document?

I can't simply limit the scrolling to areas that already have tiles, because the user needs to be able to add tiles outside that boundary. Arbitrarily creating a level size, even if it's easily changeable by the user, doesn't seem ideal either.

Has anyone seen an application that deals with this problem?
