[Simh] Graphics Terminals and Graphic System Phototypesetters

[Al Kossow]

Simulation of the output of early phototypesetters, or a Gerber 
photoplotter is a little tricky because you need the glyph information 
that was printed on the mechanism that shot the images of the characters 
onto the film output; which could be moved around in different slots 
depending on the job being typeset. Later units used high resolution CRT 
like things to form the characters.

There were a few very unique glyphs in Bell Labs' typesetter, like the
AT&T trademark
