`vertex_label_color` does not work in matplotlib backend

[pournaki]

Describe the bug
When plotting a graph inside a matplotlib axis, the vertex_label_color stays black no matter what.

To reproduce

import igraph as ig
import matplotlib.pyplot as plt

G = ig.Graph.Erdos_Renyi(10,0.1)
G.vs['label'] = range(10)

fig = plt.figure()
ax = fig.add_subplot(1,1,1)
ig.plot(G,
        target=ax,
        vertex_size=.4,
        vertex_color='black',
        vertex_label_color='white',
       )
plt.show()

Version information

Could you please try the develop branch? Lots of mpl change there

Thanks for your answer. I just uninstalled igraph and reinstalled it using

pip install git+https://github.com/igraph/python-igraph@develop

Running the above code produces significantly smaller vertices, but the label color is still black instead of white.

Ok I'll take a look today

I committed a fix in #717 which was straightforward. Should be there in the next version as soon as the PR is merged.

Thank you for reporting!

Thank you very much for fixing it! Looking forward to the new version.
