Actually, I claim that Bill's fix to pic/pltroff.c is wrong.  The comment
says:
	/* internal troff limit: 13 bit for motion */

This means that the size of the bit field for representing motions inside
of old TROFF is 13 bits.  In typesetter-independent, this field was
changed to 15 bits.  Thus the line should be:

	if (xconv(xmax) >= 32728 || yconv(ymax) >= 32768) { 	/* ... */

This internal representations are discussed in Kernighan's report
"A Typesetter Independent TROFF" (Bell Labs CS TR 97).
