What you're describing sounds vaugely like a 'snap to grid' setting for
singleTile mode. Out of curiousity, why not simply... use tiles, if what
you want is a gridded output which takes advantage of the browser cache?

Also, the 'ratio' parameter allows you to prevent a re-request of tiles
when you only drag 'a few pixels'.
