Changed so that the picking pass get drawn once in the beginning so that the AO shatde could calculate AO from the depthbuffer generated during pthe pickingpass. In the ImGUI debugg window there is now sliders to change the behavior of the AO shader. Only the minimum ambient lightning is HardCoded in to the frowardPlus fragmentshaders with a define in the begining.
