The problem is totaly implementation limited.  There is nothing that you can
do about it, except do things diffrently.  I certainly would not do charpath
flattenpath to center text.  Try (string ) stringwidth.  This will give
you the width of the string.  From there, it is fairly trivial to center the
text horizontaly.  To center the text verticaly, however, is something else.
What I'd do is to get the bounding box for the FONT from the font
directory.  This will allow you to determine the total height for the
hightest character at your font size.  Divide it by 2 and use that as 
a fixed dy value.  Actually, something other than 2 looks better.
