7.22 and CVS HEAD.

assign: igorm?

Noticeable degradation between 6.51 ps rendering and pdf generated by 7.23.
There are irregular/jagged edges, most noticeably on the left column of
bottom part of the first page.

#596394 - INTERNAL - (pdfwrite) Wrong glyph width (093-01.ps)
reported by: igorm

CompareFiles/093-01.ps generates PDF with a wrong
width of 'T' in th text "5401 Tech Circle, Moorpark C A ,
93021". Source PS has a replaced Metrics which is
missed in PDF. CVS HEAD, Windows 2000.

#596494 - INTERNAL - buggy 093-01.ps

CompareFiles/093-01.ps is either buggy or obsolete. It
redefines Times-Roman with different Metrics without
