+    \brief Strategy: line clipping algorithm after Liang Barsky
+    \ingroup overlay
+    \details The Liang-Barsky line clipping algorithm clips a line with a clipping box.
+    It is slightly adapted in the sense that it returns which points are clipped
+    \tparam B input box type of clipping box
+    \tparam P input/output point-type of segments to be clipped
+    \note The algorithm is currently only implemented for 2D Cartesian points
+    \note Though it is implemented in namespace strategy, and theoretically another
+        strategy could be used, it is not (yet) updated to the general strategy concepts,
+        and not (yet) splitted into a file in folder strategies

+\note The version in Gems didn't account for polygons crossing the 180 meridian.
+\note This version works for convex and non-convex polygons, for 180 meridian
+crossing polygons and for polygons with holes. However, some cases (especially
+180 meridian cases) must still be checked.
+\note The version which sums angles, which is often seen, doesn't handle non-convex
+polygons correctly.
+\note The version which sums longitudes, see
+http://trs-new.jpl.nasa.gov/dspace/bitstream/2014/40409/1/07-03.pdf, is simple
+and works well in most cases but not in 180 meridian crossing cases. This probably
+could be solved.
+
+\note This version is made for spherical equatorial coordinate systems

+\author Adapted from: http://williams.best.vwh.net/avform.htm
+\see http://en.wikipedia.org/wiki/Great-circle_distance
+\note It says: <em>The great circle distance d between two
+points with coordinates {lat1,lon1} and {lat2,lon2} is given by:
+    d=acos(sin(lat1)*sin(lat2)+cos(lat1)*cos(lat2)*cos(lon1-lon2))
+A mathematically equivalent formula, which is less subject
+    to rounding error for short distances is:
+    d=2*asin(sqrt((sin((lat1-lat2)/2))^2
+    + cos(lat1)*cos(lat2)*(sin((lon1-lon2)/2))^2))
