Support Wayland as a backend about penrose HOT 4 OPEN

Looking forward to this! I played a bit with penrose when looking for a programmable WM to program with rust, but then switched my system over to wayland, and haven't found any programmable compositor that I could get to the point I was with xmonad (despite my lack of haskell programming knowledge).

Some info that can be useful to you:

• I also started reading the wayland book, it's from the guy who wrote wlroots. It looks like it's hosted on SourceHut, which seems to be currently offline because of a massive DDOS attack.
• there is also jay that works as a programmable compositor to build one's tiling wm that I'm playing with.

qtile: https://github.com/qtile/qtile may be a good reference as well as they have a both a wayland and x11 backend

Thanks for the links @nabajour! Particularly the context around why the wayland book is currently offline (hopefully the source is available somewhere so I can nab an offline copy for future reference 🤞) I'd spotted jay previously but hadn't included it in my list as it looks like it handles implementing the Wayland protocol itself which probably isn't the way I'm going to go with this? Still worth a look though, just might be a little harder to unpick the pieces I want to learn from!

If I'm able to pull off what I'm aiming for then you should be able to swap out the X back end in Penrose for a new Wayland one and mostly keep the rest of your setup unchanged. I need to read up and experiment with things around how interacting with client programs works (particularly the sorts of things that you might do with something like xdotool) before I can settle on the new trait that will be replacing XConn. If you have any tips or links along those lines I'd appreciate a steer in right direction 🙂

The wayland book is still offline, but it looks like the source is available on Drew Devault's sourcehut. It's buildable with mdbook.

It's interesting to see how stuff is done from scratch, but yes, smithay might be a better starting point, or something based on wlroots. I saw some things missing in jay that depend on extensions, so those might need to be reimplemented from scratch in this case...
