Jonas Jenwald 098a56270d Normalize the BBox entry in Tiling Pattern dictionaries (issue 8117)
According to the PDF specification, see http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#G7.3982967, the `BBox` entry should have the form `[left, bottom, right, top]`.
Since some PDF generators apparently violates the specification, we normalize the `BBox` to ensure that the pattern is (correctly) rendered.

Fixes 8117.
