Extract correct PDF format version from the catalog

Browse source 
The 'Version' field of the most recent document catalog, if present, is
intended to supersede the value in the file prologue.

This is significant for incrementally-built PDF documents and generators that
emit a low version in the prologue and later apply a format version based on
PDF features used, such as Apple's CoreGraphics/Quartz PDF backend.

Fixes the internal version variable, as well as the PDFFormatVersion reported
by the API and consumed by viewers.
