Fix times in graphics doc

[kcrisman]

The docstring for show is raw (r""" ... """)
and contains

`[0,1]\\times[0,1]`

which does not render right in the
show documentation.

In a raw string, \\times becomes \\ (newline) + times.

The fix is to use \times instead of \\times.

I think I just reported this without even looking at the code - that would surely do it. Shall I trust that you verified in both html and pdf?

Ran make and make doc-pdf successfully.

Checked both html and pdf; that instance of
[0,1]\times[0,1] now renders fine in both.

Found no other similar problem needing fixing.
