Ouch no, this would be bad!
If the SLD has a filter that uses BBOX, we want it to behave like
OGC recomended, the above would turn it into a loose one too.
The idea I had was to only create the bbox filter specifically
for paint area catching, and leave whatever extra filter was
specified thru SLD or CQL as is.
