  That is correct. The layer's filter is used now when the filter 
encoding is simple enough to be transformed into a where clause 
(binary/logical operations with one spatial filer. The spatial filter 
should be a bbox and is used to set the map extents). Note also that 
this applies on layers of type Postgis, Oracle and OGR
  I am willing to work toward adding other spatial filters and layer 
types into this. I have entered a bug on this 
http://trac.osgeo.org/mapserver/ticket/2492 .
