Version 1.12, 12-Jul-2025:
File... Print outputs a single document, even when
multiple pages are required. This is particularly
valuable when printing to a PDF file or when the
printer supports multiple-pages-per-sheet options.
Version 1.11, 10-Jul-2015:
Aperture Correction scaling changed so that a value
of '1.0' (sensibly) corresponds to a 100% aperture!
Modified to be suitable for compilation by version
6.00a of 'BBC BASIC for Windows' (64-bit 'doubles'
are now explicitly declared as such with # suffix).
