bigvia draws as many vias as necessary to fill the rectangle defined by
its dx and dy arguments. The ``bigvia'' center is indicated with dx and
dy, thus making this function much like addphvia. The necessary segments
are drawn to avoid having notches or other drc rules violated.
This function is tipically used by routers when connecting two non minimal
wires, like supplies or clocks.
The values for drawing the via correctly, ie avoid drc violations, are
taken from the idps set of rules, and are not changeable at run time.
*** mbk error *** bigvia impossible : negative values dx, dy in
figure figure at (x, y)"
If either dx or dy are negative, the function complains and exits.
