Description Owen Taylor 2005-03-12 22:25:29 UTC 
gnome-print-pdf.c uses %g all over the place for printing doubles.
Now, this is sort of dubious because we generally want fixed precision
on the page, not a fixed number of significant digits.

But more importantly than that, if you end up with a number very
close to zero, then %g will give scientific notiation, which is
not supported in PDF.

I saw this for the text matrix due to a gnome_print_rotate (gpc, 90)
(producing an invalid PDF file that neither xpdf nor acroread would
load) but it can occur in almost any use of %g in gnome-print-pdf.c

All uses of %g need in the file should be replaced with %f, some will
likely need a precision specified.
