Fixed #25740 -- Documented GEOSGeometry operators.

    >>> line.coords

    ((1.0, 1.0), (0.0, 50.0), (50.0, 50.0), (50.0, 0.0), (1.0, 1.0))

Geometries support set-like operators::

    >>> from django.contrib.gis.geos import LineString

    >>> ls1 = LineString((0, 0), (2, 2))

    >>> ls2 = LineString((1, 1), (3, 3))

    >>> print(ls1 | ls2)  # equivalent to `ls1.union(ls2)`

    MULTILINESTRING ((0 0, 1 1), (1 1, 2 2), (2 2, 3 3))

    >>> print(ls1 & ls2)  # equivalent to `ls1.intersection(ls2)`

    LINESTRING (1 1, 2 2)

    >>> print(ls1 - ls2)  # equivalent to `ls1.difference(ls2)`

    LINESTRING(0 0, 1 1)

    >>> print(ls1 ^ ls2)  # equivalent to `ls1.sym_difference(ls2)`

    MULTILINESTRING ((0 0, 1 1), (2 2, 3 3))

.. admonition:: Equality operator doesn't check spatial equality

    The :class:`~GEOSGeometry` equality operator uses

    :meth:`~GEOSGeometry.equals_exact`, not :meth:`~GEOSGeometry.equals`, i.e.

    it requires the compared geometries to have the same coordinates in the

    same positions::

      >>> from django.contrib.gis.geos import LineString

      >>> ls1 = LineString((0, 0), (1, 1))

      >>> ls2 = LineString((1, 1), (0, 0))

      >>> ls1.equals(ls2)

      True

      >>> ls1 == ls2

      False
