Internal changes
-
updates in specializations/not_implemented for various algorithms (as in
an earlier version, these changes are still going on; they take care for
simplified structs, better error reporting, and automatized documentation)
-
fixes in unit tests
Breaking changes
-
points accessed through a pointer (e.g. in a linestring) should now be
specialized without the pointer. In previous versions a type
my_point
used like linestring<my_point*>
had to be specalized like: template<>
struct tag<my_point*>
. Now the library itself removes the
pointer before calling the traits class, so now it should be like: template<>
struct tag<my_point>
Bugfixes
-
intersection was sometimes wrong for integer points, fixed
-
documentation, order of parameters in simplify was wrong, fixed

Improvements on algorithms

Checking self-intersections is now not done automatically, this can blast
performance.
-
Besides that, checking self-intersections is made faster.
-
Intersections now avoid outputting duplicate points. So they output the
minimal set.

is "within or on boundary"

within<box, box>
