[gs-cvs] rev 7792 - in trunk/gs: doc src

New Revision: 7792

Modified:
   trunk/gs/doc/pscet_status.txt
   trunk/gs/src/zgstate.c
Log:
Reset the dashed line array at initgraphics. Fix CET 09-28-01.

DIFFERENCES:
There's no other Comparefiles or CET differences.

DETAILS:
pscet_status.txt marks this case as DIFF, but current version of
Ghostscript matches Tek checksum. Both Tek and Ghostscript forget to
reset the dash array at initgraphics and generate the same incorrect
checksum. This bug is fixed in CPSI-based PhotoPrint but redefinition
of halftone operators affect the PhotoPrint checksum, which doesn't
match anything else. With the proposed patch Ghostscript matches
Distiller 5, that does everything right.
