Hi,
Currently Podofo returns a zero width/height rect when
PdfPage::GetPageBox() is called on a page box not defined on a specific
page. Pdf specs (3.6.2) provide a number of fallbacks for these cases :
- ArtBox, BleedBox and TrimBox should default to CropBox
- CropBox should default to MediaBox
Here is a patch which implement those fallbacks :

return pageBox;
}
