The instructions that I offered Steve for how to set up the WMS-C layer
would probably make the alignments match. As it is right now, the WMS-C
layer is right, the other two are wrong. (I've confirmed this with tests 
of other data.) The reason is that the Google-like tiles can't be
positioned right with the current OpenLayers map parameters.

Unfortunately, changing the map parameters means I need to change them
on the server side as well -- I changed the server to accomodate the map
on OpenStreetMap.org, even though it didn't match the Google-like data,
so I'll need to change it back if the Map params on OSM.org change.
