Geodes contain geosets. Each geoset's internal geometry will
be drawn in exactly the specified order, but the ordering of
the geosets is subject to permutation when mode-sorting is
enabled (and it is, by default, for performance reasons). If
you perform an intersection traversal, the geosets are visited
in the order specified (0,1,2,...).
