Hmm.  You're right -- that it is probably what I really want -- but I
still don't understand aspect_ratio.  Why, if I change aspect_ratio
from [1,1,1] to [1,1,2], do the relative scalings of the x- and y-axes
change?  Shouldn't only the z-axis (relative to x and y) be affected?

I guess I find the behavior of aspect_ratio rather unpredictable. With

P = sphere()
P.show(aspect_ratio=[a,b,c])

it makes sense: the coordinate system, and hence the sphere, is
stretched by these factors.  However, with the plot that I mentioned
in my original post, it seems to behave oddly, as mentioned above:
changing from [1,1,1] to [1,1,2] altered the relative scales on the x
and y axes.
