Allow it to run in a desktop environment on wayland.

[cxxxr]

I could not get font-mixing and canvas examples to work in gnome on Ubuntu 23.04 wayland. I don't know the specific cause yet, but I couldn't find the issue, so I made one. As a workaround, if I use Ubuntu on xorg in gdm, it works fine.

The issue is an old GLFW being used. This should already be fixed on the latest.

Thank you for the support.

I have updated the following libraries.

• alloy
• glfw
• array-utils
• float-features
• sdf

And I have prepared a minimal code.

;; trying-alloy-example.asd
(defsystem "trying-alloy-example"
  :depends-on ("alloy"
               "alloy-glfw")
  :serial t
  :components ((:file "main")))

;; main.lisp
(defpackage :trying-alloy-example
  (:use :cl)
  (:local-nicknames
   (#:glfw #:org.shirakumo.alloy.renderers.glfw)))
(in-package :trying-alloy-example)

(defun test ()
  (glfw:with-screen (screen 'glfw:screen)
    screen))

And when I called this, I got an error.

I will continue to try, but if you have any advice I would appreciate it :pray:

[Shinmera]

Hmm, looks like the port to the new glfw library is not yet correct. I'll have to take a look once I have the time.
