gEDA: Postscript output rewrite update

[Mike Jarabek <mjarabek-at-NOSPAMistop_dot_com>]

Hi All,

	Progress on the new PostScript output is nearly complete.  Today I
added unicode font support to text printing.  The implementation uses
and adaption of Wojciech Kazubski's strategy for remapping the
postscript font.  In the original patch, there was a static table
listing a few glyphs of interest.  I have taken the full Adobe glyph
list and included the unicode to glyph name mapping in a hash table.
This should ensure coverage for most western languages.  The font
remapping is only output if unicode characters are detected in your
schematic.  Otherwise ISO-LATIN1 encoding is used.  If your glyph is
missing tell me!

	In the process I have broken the page rotation and scaling code.  I
plan to work on fixing that next, as well as streamlining the calls to
the object printing functions by removing the offset* parameters that
are no longer needed.

	I will try to make sure that all of this gets in a week before the GEDA
code sprint on the 20th. (So that I don't have to merge too many patches
into my tree! ;-)

Soon to be complete,
Mike
