[catap]

rebased to solve conflict with qt6

[mascguy]

Haven't had a chance to test with this, but definitely fine with it!

Anyone else?

[catap]

One more rebase to solve conflicts in darktable and darktable-devel.

[mascguy]

We'll wait another day or so, to give maintainers a chance to review. (And the buildbots are still catching up with various updates over the past week.)

Assuming there aren't any objections, let's plan to merge Friday evening, after 8:00pm EST.

[mascguy]

The buildbots are mostly idle at this point, apart from 10.12 and 10.14. So this is as good a time as any. Merging.

Thanks!
