Graphics Array needs suboptions to show

[kcrisman]

p1=plot(x^2, (x, -pi, pi), color='blue',legend_label="f") 
G=graphics_array(((p1,p1),(p1,p1))) 
G.show(figsize=[8,8])

... 
KeyError: 'pop(): dictionary is empty' 

This is reported at ​this sage-support thread.

I think the fix should be the same as at #10244, but for the GraphicsArray class.

Related tickets:

• #10656 - Graphics Arrays should be able to become Graphics objects
• #10657 - options should be passed to all graphics, and they should be set separately if desired

Hmm, but that doesn't work... but it must be a similar issue, anyway.

Adding the suboptions we usually send to save to the normal !Graphics class matplotlib removes the error, but does the following - see attached graphic. I don't have time to do any more with this now, though.

Note the second graph has two legends for the same function!

I should add that my code was slightly simpler:

sage: p = plot(x,legend_label='f')
sage: G = graphics_array((p,p))
sage: G

This is a bug which might be related:

sage: g = Graphics()
sage: g += plot(x,legend_label='f')
sage: g.set_legend_options(title="Nice")
sage: G = graphics_array((g,g))
sage: G.show()
...
KeyError: 'font_family'

It seems that this part of the problem might be completely solved by adding the suboptions usually added when show()'ing a graphics object.
