jtc d9789d4225 Overlay our pcvt with pcvt 3.32 sources. All of our fixes have been
incorporated into the master sources, so it is unnecessary to resolve
all the conflicts that would occur if we let CVS "merge" the versions.

Character Generator description (before it gets lost ..)
--------------------------------------------------------------------------------
The lower character generator is the default IBM character set II.
The description of the higher character generator follows below. The
character names are taken from the "Postscript Language Reference
Manual", 2nd Edition, Fourth printing July 1991, pp 596.
NOTE: The hex values here are NOT the values the character is identified
by in the emulator. The "physical" (vt220 character) to "logical"
(this table, character generator) conversion is done in the character
output routine by using the tables from file pcvt_tbl.h.
The order of the characters is not regular and was largely influenced by
the status of my brain while pixel-placing characters ....
