v4.0.0

vipsdisp has been moved on top of the updated image display widget from nip4 development.

It now needs libvips 8.17, but should be faster, smoother, rendering quality should be up, and it should handle many more corner cases, especially ones involving display modes like pages-as-bands.

Linux binary here:
