#10490: boost::geometry::difference produces a "possible loss of data" warning in
MSVC
------------------------------+---------------------------
 Reporter:  anonymous         |      Owner:  barendgehrels
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  geometry
  Version:  Boost 1.56.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------------
 Using the boost::geometry::difference function causes MSVC to emit the
 warning:

 {{{
 c:\boost\include\boost-
 1_56\boost\geometry\algorithms\detail\sections\sectionalize.hpp(612):
 warning C4244: 'initializing' : conversion from 'double' to 'const
 coordinate_type', possible loss of data
 }}}

 (full compiler output is attached)

 This is reproducible using the sample from the
 [http://www.boost.org/doc/libs/1_56_0/libs/geometry/doc/html/geometry/reference/algorithms/difference.html

 docs].

 Versions of boost prior to 1.56 do not exhibit the problem.

 This was reproduced using Visual Studio 2010 and 2013.
