py-matplotlib doesn't configure variants properly

[irony42@…]

port instal py..-matplotlib for any variants will not install the agg backend, which prevents about half the variants from actually working as advertised. A bunch more of the variants would need

post-patch {

reinplace "s|^{agg=False|agg=True|" ${worksrcpath}/setup.cfg}

}

in order to work properly. However, if it were my call I'd just edit patch-setup.cfg.diff "+agg=False" to "+agg=True" (and not give any options to turn agg off). Matplotlib's default is to include the agg backend (which does not require any additional port dependencies), and it works great on OSX, so there's not too much advantage to ever disabling it.
