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