+ add code to interpolate on finite vertices of an infinite face
they are not used by default because it's expensive, unless the macro
CGAL_MESH_2_SIZING_FIELD_USE_BARYCENTRIC_COORDINATES is defined.
Can be useful to be more precise about the sizing
That feature can be enabled with g++, clang++, and icpc (intel). It could
be implemented for MSVC, with the flag /Zs, but that is not yet done (and
probably will not).
The option is controlled by a CMake option, CGAL_ENABLE_CHECK_HEADERS, that
is disabled by default. If that option is enabled by the user, then CMake
will check if the compiler $CXX understand the syntax:
$CXX -x c++ -fsyntax-only CGAL/header.h
and send an error otherwise.
Then phony targets will be created:
- a target check_CGAL__header_h for each header <CGAL/header.h>,
- a target check_pkg_<pkg> for each package <pgk>,
- and a target check_headers for the whole CGAL.
Those new targets currently give a lot of compilation errors if
CGAL_ENABLE_CHECK_HEADERS is enabled!
+ fix several missing includes in Mesh_2.
-Wunused-local-typedefs is a new warning flag of gcc-4.7, and it will enabled
by -Wall since gcc-4.8 (not yet released).
The fix is a big set of removals of unused typedefs (or comments, or moves,
depending on the context).
Bug reported by a user against CGAL-4.0.2
A single triangle cannot be meshed!
The fault was a buggy assertion added in the following revision:

|Add an assertion that checks that a point constructed as the midpoint of an
|edge is located either on the edge or inside one of the two incident faces.

|-----------------------------------------------------------------------
And the assertion message was:
terminate called after throwing an instance of 'CGAL::Assertion_exception'
what(): CGAL ERROR: assertion violation!

Explanation: Your data set contains at least a vertex that is very close to
a constrained edge! Mesh_2 cannot mesh that sort of data set.
