Make CSDs optional/hidden by default about dwl

[djpohly]

Glad to see you're giving it a try! I'm all for canning CSDs in dwl - looking at xdg_decoration_manager from wlroots, I hope it won't be too complicated. Interested in putting together a PR?

I'll have a look but I can't promise anything - sadly don't know much about Wayland protocols or wlroots. I need to read Drew DeVault's book at some point.

For the moment you can disable the title bar in Firefox by navigating to Customize… in the menu and unchecking Title Bar.

@djpohly I see you made a commit for this 😃 I was struggling anyway, so thanks.
It doesn't appear to work yet, maybe it's still WIP. Comparing with cage's code, I think you need to call getxdecomode straight away in the createxdeco handler.

Ah, yep, the protocol description seems to indicate that we have to send an xdg_toplevel_decoration.configure event right away. Fixing now - thanks!

The recent commit added support for xdg_decoration. Firefox, however, appears to support only the older KWin server_decoration protocol (which is considered obsolete by wlroots). I still hope to support it in dwl, but it might be trickier to get working right.

That's kind of strange, unless the xdg_decoration protocol is relatively new. If sticking with the suckless theme then maybe implementing support for server_decoration isn't worth it - but that has obvious downsides.

This is, I hope, fixed in commit 9071ce6. Could everyone test your variously decorated programs with the latest Git to see if client-side decorations still show up anywhere (and if they do, check sway as well)?

Sorry, would love to test it when I get time. You have probably validated it yourself too 👍
