wm_xr_draw_view()

void wm_xr_draw_view	(	const GHOST_XrDrawViewInfo *	draw_view,
		void *	customdata
	)

Draw a viewport for a single eye.

This is the main viewport drawing function for VR sessions. It's assigned to Ghost-XR as a callback (see GHOST_XrDrawViewFunc()) and executed for each view (read: eye).
