When using user-defined fonts, the characters all appeared on top of one another in the wrong place. After only a couple of hours of work, nrh@bellcore.com fixed the problem; his patch is below. Ghostscript now correctly renders a number of files using user-defined fonts, including (GET THIS ONE) a TeX document postprocessed by dvitps.

Thanks for submitting this bug fix. Hitoshi Aida sent in a similar
one. A fix equivalent to this will be in release 1.4.
