_latex_ method of generic graphs does not support all advertised options (vertex_color, vertex_shape, ...)

[cyrilbouvier]

Steps To Reproduce

G = graphs.PathGraph(2)
G.set_latex_options(vertex_shape='rectangle',vertex_color='red')
view(G)

Expected Behavior

A graph with vertices represented as red rectangle should be displayed.

Actual Behavior

A graph with vertices represented as black circle (the default) is displayed.

Additional Information

If one looks at the latex code generated, one can see the option shape=rectangle for the \Vertex but it does not seem to have any effect. The same is true for the color: draw=cv0 is present, where cv0 is defined as the color red (via \definecolor{cv0}{rgb}{1.0,0.0,0.0}), but it does not seem to have any effect.

\begin{tikzpicture}
\definecolor{cv0}{rgb}{1.0,0.0,0.0}
\definecolor{cfv0}{rgb}{1.0,1.0,1.0}

\definecolor{cv1}{rgb}{1.0,0.0,0.0}
\definecolor{cfv1}{rgb}{1.0,1.0,1.0}
\definecolor{clv1}{rgb}{0.0,0.0,0.0}
\definecolor{cv0v1}{rgb}{0.0,0.0,0.0}

\Vertex[style={minimum size=1.0cm,draw=cv0,fill=cfv0,text=clv0,shape=rectangle},LabelOut=false,L=\hbox{$0$},x=0.0cm,y=2.5cm]{v0}
\Vertex[style={minimum size=1.0cm,draw=cv1,fill=cfv1,text=clv1,shape=rectangle},LabelOut=false,L=\hbox{$1$},x=5.0cm,y=2.5cm]{v1}
