[zbsgujnx] Lowercase pi

Here is a page of pi in old-style numerals.  We use text figures, large type, and double-spacing all to make it easier to read.

LaTeX source code.  Also available in the same directory is the square root of 10 written out in the same way.  The square root of 10 seems a more appropriate number to write out in many digits of base 10.

Proportional spacing was accomplished with cfr-lm, but it is not available in math mode.
