Comment (by ksgeograf):

 You are right. However, the current OGR implementation only supports
 "Envelope Intersect" and "Intersect" (look in ApplyFilter).

 If the BBOX filter is removed from the OGR call, then there would be extra
 strain on the OGR provider, since it now recieves all/more features. I
 guess that would slow down the rendering operation which is purely
 dependant on envelope intersection.

 I guess it could be handled in ApplyFilter, so the geometry filter is
 cleared if the spatial operation is something other than
 intersection/envelope intersect.
