Change from using xdg shell v5 to v6.

[etherealvisage]

As mentioned in #6 , sway uses zxdg v6, not xdg v5. I'm no expert in Wayland or xdg-shell, but from an hours' work poking around I managed to get st running on sway using zxdg v6. Seems to be working well, but I'd welcome some code review.

I'm not expecting this to be merged, but including a new branch with this support would be awesome.

Thanks!

Fixed issue for me. I'm using a custom compositor, but I believe this issue will impact all consumers of wlc

May've fixed #4, but I haven't updated for awhile

Good. Other parts of Velox should be fixed also.

Thanks for this! I found that currently on my Intel machine I need to add the following patch on top of your commit otherwise I get a "xdg_surface has never been configured" error and st crashes:

I found the solution to this issue here: https://patches.videolan.org/patch/20875/

@Shugyousha added that commit to the branch. Ran a quick test and it doesn't break anything, so . . . good enough for me. :-)

Since the xdg shell protocol is currently stable, here is a commit to use the stable protocol, for those who care. This is necessary to use st on swc, for example, as it would segfault on anything but stable.
