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
