The following snippet produces an output with nice curvey edges: ```` from graph_tool import load_graph, Graph from graph_tool.draw import graph_draw
g = Graph()
g.add_vertex(4)
pos = g.new_vertex_property('vector<float>')
pos[g.vertex(0)] = [0, 0]
pos[g.vertex(1)] = [0, 1]
pos[g.vertex(2)] = [1, 0]
pos[g.vertex(3)] = [1, 1]
g.add_edge(g.vertex(0), g.vertex(3))
g.add_edge(g.vertex(1), g.vertex(2))
g.vertex_properties['pos'] = pos
ctl = g.new_edge_property('vector<float>')
for e in g.edges():
ctl[e] = [0, 0, 0.25, 0.2, 0.75, 0.2, 1, 0]
graph_draw(g, pos=g.vp.pos, edge_control_points=ctl, output='tmp.eps')
````
But when I replace the graph here with one loaded from the attached .gt
file, I get no edges drawn at al. If I take out the `pos` argument though,
the curvey edges come back. Suggestions for getting both positions and
curvey edges?
