8.3.9 Bad bounding boxes from latex_vis

Very tall program visualizations are susceptible to Ghostscript bug #202735, “bbox device doesn’t allow min coords < 0”. latex_vis attempts to work around that bug by defining a large PostScript ImagingBBox as described in While no problems with the latex_vis workaround have yet been reported, if problems do occur it should be sufficient to set the GS environment variable to ‘:’ or the name of a program known not to exist. latex_vis will then issue a warning message and generate an EPS file with an acceptable but slightly loose bounding box, as mentioned in The latex_vis backend.
