Detailed Description

Terminal Independent Graphics Display Package.

Mike Muuss July 31, 1978

This routine is used to plot a string of ASCII symbols on the plot being generated, using a built-in set of fonts drawn as vector lists.

Internally, the basic font resides in a 10x10 unit square. Externally, each character can be thought to occupy one square plotting unit; the 'scale' parameter allows this to be changed as desired, although scale factors less than 10.0 are unlikely to be legible.

The vector font table here was provided courtesy of Dr. Bruce Henrikson and Dr. Stephen Wolff, US Army Ballistic Research Laboratory, Summer of 1978. They had developed it for their remote Houston Instruments pen plotter package for the GE Tymeshare system.

Used by LIBPLOT3 and LIBRT for simple vector fonts.
