#10659: svg_mapper output is offset for int-based point type
----------------------------------------+---------------------------
 Reporter:  Volker Schöch <vschoech@…>  |      Owner:  barendgehrels
     Type:  Bugs                        |     Status:  new
Milestone:  To Be Determined            |  Component:  geometry
  Version:  Boost 1.56.0                |   Severity:  Problem
 Keywords:  svg_mapper, integer         |
----------------------------------------+---------------------------
 Based on the example from the
 [http://www.boost.org/doc/libs/1_56_0/libs/geometry/doc/html/geometry/reference/io/svg/svg_mapper.html

 documentation] I find the following oddity: Simply change the following
 line
 {{{
 typedef boost::geometry::model::d2::point_xy<double> point_type;
 }}}
 into
 {{{
 typedef boost::geometry::model::d2::point_xy<int> point_type;
 }}}
 Nota bene: All values in the example code are integral numbers, anyway.
 Yet, the resulting output is different, see attached files. In case of
 int, the entire graphic is considerably offset to the north.
