" special: Literal PostScript

For simple graphics, or just for experimentation, literal PostScript code can be included. Simply use a \special beginning with a double quote character `"'; there is no matching closing `"'.

For instance, the following (simple) graphic:

was created by typing:

\vbox to 100bp{\vss % a bp is the same as a PostScript unit
  \special{" newpath 0 0 moveto 100 100 lineto 394 0 lineto
  closepath gsave 0.8 setgray fill grestore stroke}}

You are responsible for leaving space for such literal graphics, as with the \vbox above.
