Comment:

 I think this is a great change.  I agree that we should use
 {{{maxResolution}}} and {{{numZoomLevels}}} instead of
 {{{restrictedMinZoom}}}.

 I've attached an updated patch with a few changes:
  * patch applies at r12088
  * the isValidZoomLevel asserts that -1 is '''not''' valid (was failing
 before by asserting that valid was true)
  * updated docs in bing-tiles-restrictedzoom.html to suggest using
 maxResolution and numZoomLevels instead of restrictedMinZoom
  * updated bing-tiles-restrictedzoom.js to use the same layer with three
 different sets of resolutions, more clearly demonstrating what this patch
 allows

 Tests pass and examples work in Chrome 12 and IE 6.  Please commit (after
 #3342).
