//! \page main_vectorfont_intro Introduction
//!
//! A Hershey Simplex Roman vector font is used for drawing text on the CNC
//! machine.  The Hershey font is a public domain vector font comprised of
//! numerous type faces and stroke widths.  The simplex version has a single
//! stroke per line in the character (for example, there are three strokes in
//! the letter "H", two vertical and one horizontal).  The roman face is the
//! default Hershey font, and is a sans serif font face.
//!
//! The data in this font array is based on the data created by Paul Bourke
//! from the Hershey font data; the original data is available at
//! <a href="http://local.wasp.uwa.edu.au/~pbourke/dataformats/hershey">
//! http://local.wasp.uwa.edu.au/~pbourke/dataformats/hershey</a>.
//!
//! The Hershey Fonts were originally created by Dr. A. V. Hershey while
//! working at the U. S. National Bureau of Standards.
//!
//! The array containing the Hershey vector font is contained in
//! <tt>main_micro/vectorfont.c</tt>, with <tt>main_micro/vectorfont.h</tt>
//! containing the API defintions for use by the remainder of the application.

//
//! The Hershey simplex vector font.  There is one string per character, and
//! each string is formatted as follows:  the first byte is the number of
//! coordinate pairs in the character, the second byte is the width of the
//! character (including white space), and the remaining bytes are the
//! coordinate pairs (with "\377\377" indicate a pen lift).
