LIGHTING !!!!! finally

This was not easy, and yet it was made so much easier by having done it once before last year. I added support for a directional light, a dynamic (aka not hard coded, so pratically infinite amount of) point lights and spot lights, full PBR, and I also made a little handy editor to go along with it, although that’s not in the renderer that’s just in the demo project. Anyways, this was an incredible journey filled with pain and suffering like never before, and I’m so glad I’m through it all.
And if this was a challenge, I don’t know what shadow mapping is going to be, which is going to be basically right now, I’m going to add tanget space normal mapping and then it’s already shadowmapping. I’m mentally unprepared, but oh well what can I do?
