Bring in Tim Schaub's "Graphic" layer as "Layer.Image" (since in the future,

'graphic' may mean something different, like SVG graphic). Tests, docs, example, and library change. Thanks, Tim! git-svn-id: http://svn.openlayers.org/trunk/openlayers@1712 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf

+    <p>
+        The "City Lights" layer above is created from a single web accessible
+        image.  If you construct it without any resolution related options,
+        the layer will be given a single resolution based on the extent/size.
+        Otherwise, it behaves much like a regular layer.  This is primarily
+        intended to be used in an overview map - where another layer type
+        might not make a good overview.
