The patch in question

According to PDF format reference
(http://partners.adobe.com/public/developer/en/pdf/PDFReference.pdf) and the
behaviour of other software such as Adobe reader, the type of "D" (duration)
property of the transition effect is "number" rather than "integer", which
means it can also be real. Right now, poppler always interprets non-integer
durations as 1 second, so short (< 1s) transitions become impossible, for
example.

I'd like to suggest a patch which fixes that, while preserving binary
compatibility as much as possible (changes to the glib wrapper aren't included
here).

Is this a right way to go, or should I just forget about binary compatibility
(source code compatibility will be preserved anyway)?
