NeoOffice adds experimental VoiceOver support

[pluby]

After much work, we have finally succeeded in making the LibreOffice macOS accessibility code work within NeoOffice's multithreaded architecture. With this change, NeoOffice now has experimental support for VoiceOver and possibly other macOS accessibility features.

You do not need to wait until the next release to try out VoiceOver within NeoOffice. You can try out VoiceOver now by downloading and installing the one of the following test patches:

NeoOffice 2022.1 Mac App Store:
https://github.com/neooffice/NeoOffice/releases/download/NeoOffice-2022_1/NeoOffice-2022.1-Patch-0-Test-1-Universal.dmg

NeoOffice 2022.1 Professional Edition:
https://github.com/neooffice/NeoOffice/releases/download/NeoOffice-2022_1/NeoOffice-2022.1_Professional_Edition-Patch-0-Test-1-Universal.dmg

Important warning: This feature is still in the experimental stage. We had to make significant changes to LibreOffice's code to run within NeoOffice's multithreaded event dispatching code so we expect that there are still undiscovered hanging or crashing bugs. We already know of a Calc hanging bug when using VoiceOver.

If you encounter a hanging or crashing bug while using VoiceOver or any other macOS accessibility features, feel free to create a bug report in the NeoOffice issue tracker. It would be very helpful if you can attach a crash log or, for hangs, a sample from the Activity Monitor application to your bug report.
