tachyon 3d plotting of graphs is still screwy

[williamstein]

This looks like crap:

g = graphs.DodecahedralGraph()
g.plot3d(viewer='tachyon')

but this looks good:

g = graphs.DodecahedralGraph()
show(g.plot3d(engine='tachyon'))

Also, this doesn't work (show a plot) at all:

g = graphs.DodecahedralGraph()
g.plot3d(engine='tachyon')

That's at least 2 bugs / sloppinesses.

I've uploaded the outputs (for me) of the examples.

plot1.png:

g = graphs.DodecahedralGraph()
g.plot3d(viewer='tachyon')

plot2.png:

g = graphs.DodecahedralGraph()
show(g.plot3d(engine='tachyon'))

Why is the first plot way worse than the second?
