[igraph] Drawing graph with igraph 0.5.2 and Python

[Domenico Conti]

Can I draw a dashed arcs? and also, when the edge is 'bidirectional (that is
from A to B and from B to A), I can separate the edges, so we can see the
edge that goes from A to B separated from the edge that goes from B to A ?
In my Reference Manual of Python - iGraph 0.5.2 I don't find curved parameter.
