Description
See this ask.sagemath.org question. The original poster points out that
(plot(1+e^(-x^2), xmin=-2, xmax=2, ymin=0, ymax=2.5, fill=0.5, fillcolor='green', fillalpha=0.5)).save('t.eps')
doesn't actually save with the correct fill. A simpler example is comparing
sage: polygon([(0,0), (1,1), (0,1)],alpha=.1).save('test.pdf') sage: polygon([(0,0), (1,1), (0,1)],alpha=.1).save('test.eps')
Is this a Sage or matplotlib issue?

It's a bug in mpl.

And here is the response - that PostScript doesn't actually support this. Well, now what?

Replying to kcrisman:

It seems only some backends can make eps look like it supports transparency. So, now I would say that this ticket should be closed as "invalid". ;) If someone needs transparency with eps, then they should save it to some other format and then convert it to eps.

My thus far unsuccessful attempt. I always forget something when trying to use mpl natively, and this is no exception. I think I just need a week to memorize the mpl workflow.
Unfortunately this doesn't work for some reason (empty plot other than frame). Maybe I added the plot too early.
