I'm not sure the ScaleFilterLayer handles plugins defined without
explicitly defining the PlugInLayer in the properties, and then
defining the plugin in the PlugInLayer properties.
The LayerHandler, which reads the openmap.layers property list and
creates the layers, is smart enough to check to see if the object in
the list is a PlugIn, and will create the PlugInLayer for that new
PlugIn. The ScaleFilterLayer doesn't do this (I'd say this is an
oversight).
