Didn't know that, thanks Daniel.  We just have to determine if it's
GeoPrisma's responsibility to tell the user that some OpenLayers map
options conflict with one another.  Maybe it's whatever control that
needs units that should do these tests (in our case "measure") ?  That's
an OL control though (Measure.js).
