Comment:

 I did a bit more thinking on this and some research in the OpenLayers code
 base.  I'm still not exactly sure but what happens if we set the
 following:

   * on a layer:
     * maxExtent: null
     * alwaysInRange: true
     * displayOutsideMaxExtent: true
   * on a map:
     * fractionalZoom: true

 I think then the maxResolution will be ignored and we don't really need to
 know what it is.

 The alwaysInRange property seems to be the key to supporting this, but it
 is only in OpenLayers 2.7 so we definitely can't do this in Fusion 1.1.

 We also need to establish a way to determine how to establish max extent
 in the application definition (could be another extension) - it wouldn't
 be available directly through studio but it could be set manually.
