  30  *  This file contains a very simple set of routines which might
  31  *  be shared by preprocessors.  It allows a preprocessor to indicate
  32  *  when an inline image should be created.
  33  *  This string is intercepted by pre-grohtml and substituted for
  34  *  the image name and suppression escapes.
  35  *
  36  *  pre-html runs troff twice, once with -Thtml and once with -Tps.
  37  *  troff -Thtml device driver emits a <src='image'.png> tag
  38  *  and the postscript device driver works out the min/max limits
  39  *  of the graphic region.  These region limits are read by pre-html
  40  *  and an image is generated via troff -Tps -> gs -> png
