Ok, then maybe it is not a bug, using cairo_save/cairo_restore also
makes generated pdf files smaller for program that draws only text and

% ls -l out.pdf out-save-restore.pdf
 -rw-r--r-- 1 eugen eugen 910407 2007-04-04 23:43 out.pdf
 -rw-r--r-- 1 eugen eugen 820453 2007-04-04 23:43 out-save-restore.pdf

maybe it should be recomended in documentation to use save/restore for
multipage pdfs?
