The pointer to the global wl_display object used by the
Wayland video backend.
Defined in <SDL3/SDL_video.h>
#define SDL_PROP_GLOBAL_VIDEO_WAYLAND_WL_DISPLAY_POINTER "SDL.video.wayland.wl_display"Can be set before the video subsystem is initialized to import an
external wl_display object from an application or toolkit
for use in SDL, or read after initialization to export the
wl_display used by the Wayland video backend. Setting this
property after the video subsystem has been initialized has no effect,
and reading it when the video subsystem is uninitialized will either
return the user provided value, if one was set prior to initialization,
or NULL. See docs/README-wayland.md for more information.
