[Lib2geom-devel] Method for "fuse two paths at a common point"

[mathog <ma...@ca...>]

Geom::Piecewise<Geom::D2<Geom::SBasis> > P1; // N points assigned
Geom::Piecewise<Geom::D2<Geom::SBasis> > P2; // M points assigned

where P1's last point is the same as P2's first.  The slopes
on both sides of that common point are correct too because P1 and P2 
are
subpaths of a common path.  What is (pseudocode)

   P1.fuse(P2);

to leave P1 with N+M-1 points and the segments beginning/ending on the 
common point fused?

Presumably it isn't:

    P1.concat(P2);

because, as I think I understand it, concat would leave two copies of 
the common point and
would not fuse the draw operation through it.

Thank you,
