title: OpenLayers as a large (changing and growing) image viewer
body: <p>Basically, what I'm trying to do is use a map viewer as an image viewer with the same sort of efficient tile-loading, zoom/pan awesomeness without having to build it myself.</p>
  
  <p>Specifically, I need an image viewer that will allow the image to grow and change while not altering the coordinates of any older (unchanged) tiles. This means that the center point (0,0), where the image started growing from, must always remain (0,0). So I'm looking for a library that will allow me to use a very basic Cartesian coordinate system (no map projection!), which will ask for tiles infinitely in all directions with no repetition (as opposed to how map libraries just ignore y-axis above and below the map, but the x axis repeats).</p>
  
  <p>There's another catch. I need zoom level 0 to be zoomed <em>in</em> all the way. Since the image is constantly growing, there's no way to tell what the max zoom level will be, and the coordinates need to be based on the base image layer tiles so that every tile in zoom level z contains 2^z base layer tiles.</p>
  
  <p>I am wondering if this is possible with OpenLayers and how to do it. If it's not, any suggestions of other (open-source javascript) libraries that can do this would be very appreciated! I've tried playing around with <a href="http://polymaps.org/" rel="nofollow">Polymaps</a>, but the documentation is lacking too much for me to be able to tell if it will work. So far no luck.</p>
  
  <p>Please let me know if none of this made sense, and I'll try to include some images or better explanations. Thanks! </p>
