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.
