New PDI sizing: 1600 wide x 1200 high pixels

As from September 2019, Shaftesbury Camera Club will be adopting the new PDI standard of 1600 x 1200 pixels that is being used by WCPF and many other clubs.  Fortunately the software we routinely use (Dicentra and Faststone) detects the projector native resolution and rescales on the fly to match.  This means a full 1600 x 1200 image will be rescaled downwards by exactly 10% to accommodate our 1920 x 1080 projector, i.e. the image will be presented as 1440 x 1080.
