Matplotlib 3.0 - update ok?

[Steffen Möller <steffen.moeller@uni-rostock.de>]

Hello,

I am keeping me busy packaging the Orange machine learning library that 
seems nice (https://orange.biolab.si/#Orange-Features). Now, the test 
routines demand a matplotlib.pyplot module that is not in version 2 that 
we feature. Version 3 is the current stable release.

Now, I am tempted to create a package matplotlib3 instead of forcing 
everyone to update from this long term release (see 
https://matplotlib.org/).

Any opinions from your sides?

Cheers,

Steffen
