connecting connectors to connectors (wish, in order to make constrained figures)

[Fabrice Neyret]

It would be really useful to be able to connect directly two connectors togather without explicit connecting object:

One of the strong limitation of most vector graphics tools is too make math figures: these implicitely contain constrained lines. When you want to edit such a figure (for instance to move a bit a vertex or an edge) this turns into a nightmare of one-by-one manipulation of lines strokes. Worse when you intend to represent a 3D geometric construction.

Being able to directly connect connectors together would be a convenient way to implement most of this feature (expected by everyone having to sketch geometric stuff).
