How does it get the image of an application inside of SimulaVR? Is it something weird like grabbing a graphics buffer? Or is it launching the applications as a child process so it can access its viewport? Or is it asking the windows manager? I'm not sure how this part works and am curious.

We implement a Wayland compositor interface via `wlroots`. Windows can launch like usual in our environment (i.e. via DISPLAY or WAYLAND_DISPLAY).

X11 apps are supported via Xwayland.
