[Xastir] Dbfawk font_size

[Troy M. Campbell]

I accidentally discovered the symbolic link/2 dbfawk files method.  It
_is_ kind of squirrelly but works.  My only concern is that this isn't
considered "normal behavior" for a program and someone will "fix" it one
of these days.

This is not possible directly through dbfawk.  The dbfawk language is
limited to setting a few specific internal rendering variables based on
the contents of the DBF file, and there's no way to *read* xastir
internals such as zoom level from a dbfawk file, only *set* them.  To
accomplish what you want through dbfawk alone would require enhancements
to the dbfawk language.

Yeah, hokey, but a usable workaround given dbfawk's limitations.
