If I do p.show(figsize=[500,500]) then *boom* and I know I'm doing
something wrong as the traceback tells me so :-)

ValueError Traceback (most recent call last)
...
ValueError: width and height must each be below 32768
But the thing is, I was able to do p.show(figsize=[16,16]) and
received a complex plot. With Sage 3.4.1, the docstring for show()
says:
``figsize``- [width, height] (same for square aspect)
so I thought I was allowed to pass the image width and height in as a list.
