Are there any plans for using GTK+3 for the message box features? The current implementation, as far as I know, isn’t implemented in Wayland because it doesn’t expose window primitives like X11 does and the plain X11 windows are just… ugly. Like really ugly.
SDL2 already links to libdl, so why not load up GTK+3 and call its functions instead? You’d have a hard time finding a Linux distribution that doesn’t ship it by default.
