wip: devdraw: wayland support

hdonnay commented 2 years ago

Absolutum obsoletum

I'm currently using this day-to-day, but there's a few things I need to do before I think this is ready:

[x] Implement two-edge resizes (e.g. click lower-right corner allows you to resize in both dimensions)
[ ] There's flickering when resizing
[ ] Pretty sure there's some races around reading and writing to the big window struct
[ ] Need to take a style pass
[ ] Documentation
[ ] src/cmd/snarfer
[ ] Need to figure out how much Linux application-specific stuff is acceptable in the repo (e.g. XDG desktop files?)

Some notes on what this is doing:

devdraw was unconditionally calling the "native" free for Memimage *, so this changes that
the 9l script gains special casing around wayland because the real name of the libraries (wayland-client and wayland-cursor) don't play nice with the AUTOLIB macro.
Adds a WSYSTYPE for wayland and makes that work in the relevant places

Some notable features:

Pointer warping works! (The running X11 devdraw under XWayland+GNOME doesn't work currently, but this may be a GNOME bug)
Cursor swapping works

I am unable to get it working on my system (fedora 36/ nvidia gpu):

% /usr/local/plan9/bin/acme
app_id: /usr/local/plan9/bin/acme
[destroyed object]: error 1: invalid width, height or stride (1600x1200, 6400)

should it work with nvidia or this is expected?

ah, I think that's a HiDPI bug. I'll look into it when I get a chance.

I wanted an easier way to build and install this, so I went and modified the plan9port-git AUR package and created plan9port-wayland-git.

This won't work for wlroot based compositor such as sway. Because they only support version 2 of xdg-shell
