30 Nov 1988	ehgCopied from /n/bowell/usr/src/cmd/pic. 16 Jan 1989	ehgUpdates from /n/coma/usr/bwk/pic.Brian picked up printlf() and I moved space() in openpl() in pixel and 4014,	so no changes were needed in the source imported from bowell and bwk.bwk's print.c calls arc(), which is translated in pl$DEV.c into a call to	devarc() whose code is in lib$DEV/arc.c.I didn't understand howard's dotline change and it conflicted	with using pure bwk code, so I commented it out in pltex.c. 8 Sep 1989	hwtUpdates from /n/bowell/usr/src/cmd/picSome changes in linegen.c (bigger buffers), misc.c, picl.l, picy.y, symtab.cI removed the \t-><tab> transformation in picl.l (bwk agreed it was bogus).Put the dotline change back in (to get smaller output files, and avoid	problems where lines were bunching together). 11 Sep 1989	hwtWent back to troff dotline (the postscript one doesn't act the same	as troff when scale!=1).Changed default pen size from 8 to 9 (to give same thickness lines	as default pic), and made dots change size with pen size.
