The following MetaPost program 'does the right thing'. And should
provide a guide for positioning _any_ LaTeX text as one would hope.
Turns out it was pretty simple, once you wrap your head around
MetaPost. (I got some help from Usenet). We can throw two simple
macros into the MetaPost boilerplate, and everything should be easy.
