multiple pages pdf [FR]

[kongdd]

Is it possible to add the feature of multiple pages pdf for savefig?
It is hard to inspect results with gif.

there was a similar topic on discourse: https://discourse.julialang.org/t/save-multiple-plots-on-separate-pages-of-one-pdf/41953

tl;dr: Right now, you need to use an external tool. We do accept PRs ;)

I have just tested:

io = open("fig/plot.pdf", "w")
show(io, MIME("application/pdf"), plot_somehting(1))
show(io, MIME("application/pdf"), plot_something(2))
close(io)

only shows the second plot.

sciapp/gr seems to support multipage pdfs (https://github.com/sciapp/gr/blob/ab157a8789fe6c2db886e6ede19b8d2c61dd632b/lib/gks/pdf.c#L904). Makes me wish I knew C so I could help figure this out. Plots.pdf(::Animation) would save me quite a bit of trouble around now :D
