pdfwrite - don't attempt to keep co-ordinates <32K when creating PDF 1.5+

Bug #697098 "pdfwrite charpath conversion problem"

When the PDFCompatibilityLevel is 1.5 or above we can use reals with
sensible ranges, instead of the +/- 32767 that old versions of the
specification limited us to.

This results in a large number of small differences, some minor progressions
