Bug#731140: ghostscript: on PDF files with embedded fonts, ps2pdf changes the way fonts are rendered



Package: ghostscript
Version: 9.05~dfsg-8
Severity: normal

ps2pdf should not change the embedded fonts except by optimizing them
(e.g. compressing them), but a simple test shows that it changes the
way fonts are rendered. I've attached 3 files.

font1.pdf is the original file (generated by pdflatex).
font2.pdf is the file obtained with "ps2pdf font1.pdf font2.pdf".
font.png shows the text of font1.pdf (left) and font2.pdf (right),
as obtained with xpdf.
