[Development] Stepping down as maintainer

[Gunnar Sletta]

Hi,

After quite some time of not being active in Qt, I am now formally stepping down as maintainer. It has been a great ride, but I simply don't have time to follow up Gui and Scene Graph and it makes sense that the people who are active in these areas also become the go-to guys.

I've already spoken with Eskil and Lars, and propose the following list of people to formally take over my areas:

Tor Arne Vestby - QPA and window system integration
Laszlo Agocs - OpenGL/Vulkan
Eirik Aavitsland - Image Formats and QPainter
Andy Nichols - Scene Graph

(Other specific maintainers in QtGui stay unchanged)

Thanks,
Gunnar
