-/* Theory in e-mail from J.F. Barraud
-Let B be the skeleton path, and P the pattern (the path to be deformed).
-
-P is a map t --> P(t) = ( x(t), y(t) ).
-B is a map t --> B(t) = ( a(t), b(t) ).
-
-The first step is to re-parametrize B by its arc length: this is the parametrization in which a point p on B is located by its distance s from start. One obtains a new map s --> U(s) = (a'(s),b'(s)), that still describes the same path B, but where the distance along B from start to
-U(s) is s itself.
-
-We also need a unit normal to the path. This can be obtained by computing a unit tangent vector, and rotate it by 90°. Call this normal vector N(s).
-
-The basic deformation associated to B is then given by:
-
-   (x,y) --> U(x)+y*N(x)
-
-(i.e. we go for distance x along the path, and then for distance y along the normal)
-
-Of course this formula needs some minor adaptations (as is it depends on the absolute position of P for instance, so a little translation is needed
-first) but I think we can first forget about them.
