\class QLandmarkIntersectionFilter
\brief The QLandmarkIntersectionFilter class provides a filter which intersects the results
of its constituent filters.
\inmodule QtLocation
\ingroup landmarks-filter
\since 1.1
Conceptually it performs an AND operation and thus may be used to
select landmarks which match all of it's constituent filters.
If the intersection filter contains a proximity filter at the top level (i.e. which is not nested
inside another filter) then the landmarks will be sorted by distance according to that filter.
Note that a using sort order other than QLandmarkSortOrder (i.e. no sort) will override the
sorting by distance).
Whether an intersection filter can be comprised of
compound filters (i.e. union or intersection filters) is backend specific.
Even if this is supported the performance of such a filter is likely to be poor.
