 Visibility testing
 ==================
 
+In visibility testing we gather the visible renderables of MS and BS and the lights for IS. Also for every visible light we gather the renderables.
+
+Real flow:
+
+	- Set all nodes to not visible
+	- Gather all renderables and lights 
+	- For every light that casts shadow get renderables

+- What happens in a second pass for other camera (for split screen for example). Now the renderings happen sequential so no problem. It may fuck up the visibility vectors
