In some cases, the direction of the edges in the graph is reversed compared to the results obtained from the Gremlin query.

[zz1874]

Describe the bug When generating a graph of multiple layers, it happens that the direction of the edges in the graph is reversed compared to the results obtained from the Gremlin query. But if we generate a graph with one single edge, the direction is not reversed.

To Reproduce If we put in a Gremlin query like

g.V().has('pname','gtk+3')
.repeat(outE().inV().simplePath())
.until(has('pname','libGL'))
.path()
.by('pname')
.by('label')

to generate the dependency graph between gtk+3 and libGL, the result would be .

However, if we generate the dependency graph between libepoxy and libGL by querying

g.V().has('pname','libepoxy')
.repeat(outE().inV().simplePath())
.until(has('pname','libGL'))
.path()
.by('pname')
.by('label')

, the result would be

Expected behavior In the first graph, the edge between libepoxy and libGL should be directed from libepoxy to libGL instead of the reversed way.
