This fixes a problem with generating Segment_voronoi_2.moc:
opt/local/include/boost/type_traits/detail/has_binary_operator.hp:50:
Parse error at "BOOST_JOIN"
The problem did not appear before installing boost 1.53 with macports.

In the case when q and t have the same support, the following
assertion is too strong:
CGAL_assertion(
same_points(q.source_site(), t.source_site()) or
same_points(q.source_site(), t.target_site()) or
same_points(q.target_site(), t.source_site()) or
same_points(q.target_site(), t.target_site()) )
This fixes a bug in the input br89.cin:
s 10 120 60 20
s 60 40 70 60
s 30 110 100 40
s 8 56 180 160
Probably, a similar assertion has to be removed that has to do
with r and t.

I have also added some assertion that false is
returned when t and the point among p and q share
a coordinate.
Bug fix for 1seg2ptproblem.cin input:
s 10 120 60 20
p 60 40
p 70 40

A similar fix is probably required for fecf pqrt case,
when p is segment and q is a point. The fix works when
vertices (p,q,r) and (q,p,inf) are not on different arcs
of the Linf parabola of p and q.
Explanation for arcs:
The Linf-perpendicular line to q that passes through p partitions
the Linf-parabola of p and q in two arcs.

The script ipe2cin converts all segments and points
in the first page of the ipe file given as the command
line argument to the SDG Linf cin format for segments
and points. The result is printed to the standard output.
Use refirection to save to a .cin file.
The file ipe2cin.lua has to be put in the appropriate
place, e.g., ~/.ipe/scripts/ and here is an example use:
ipescript ipe2cin ipe1.ipe > ipe1.cin

Several changes:
Reintroduce assertion for infinite faces in find_faces_to_split.
Use orientation_2_object instead of orientation_L2_2_object
in is_linear_chain.
Make primal agnostic to type of bisector line, ray, and segment.

Also, try to see if it is possible to use vertex conflict
instead of the orientation Linf test in insert_third.

The changes fix several bugs.
One choice involves a specific choice of bisectors to
compute the vv of three segments, that gives priority
to axis-parallel segments and segments that have a common
endpoint.
Maybe these changes should be also translated to vring.

New predicates in Basic_predicates_C2.h:
is_site_h_or_v
is_site_horizontal
is_site_vertical
These predicates are used in several files in classes that are derived
from Basic_predicates_C2.
