Sway, Wayland, and Xwayland

[Dale Brazelton]

Even after implementing all the suggestions from Jan I was unable to get firefox to work in sway, neither natively in wayland or with xwayland. After spending a good part of yesterday testing it, I'm convinced my problems are due to the implementation of amdgpu in FreeBSD 12 stable. For example, I could only run sway once per boot. If I ever exited sway and tried to restart it my computer would hang and I'd have to power it off. (I realize I'm probably the only person in the world trying to run a FreeBSD desktop on an amd Vega 64 graphics card!) I'll postpone further testing until we have a more up to date amdgpu, mesa, xorg-server, and xwayland in 12 stable. Thanks to everyone for your help and suggestions!

Looks like this is fixed in Xorg 1.20.  I built my xorg-server and
xwayland packages from our dev branch here
https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FFreeBSDDesktop%2Ffreebsd-ports%2Ftree%2Ffeature%2Fxserver-1.20&data=02%7C01%7C%7C8d0d2c69c1c54b08b87908d6efc8fc0b%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636960043831829889&sdata=B3tydJ2J7N3qUWAO47A9fxZFwOOZB%2BLPz%2B4x%2Bp%2FKuOQ%3D&reserved=0
and tested myself.

Hopefully we can get 1.20 out soon...
