Implementing Deferred lighting into Source 2013

Having deferred lighting in your mod comes with quite a lot of upsides as with it, you can have volumetric lighting, realtime shadows and lighting from the sun and from other light sources, while still keeping the performance steady which is something that Source's regular dynamic light entities would be incapable of (aka projected textures).

Implementing into your Source 2013SP mod

Now we are going to use Lambda Wars's implementation for it as its an enhanced/upgraded version of Alien Swarm Deferred's.

This article or section needs to be cleaned up to conform to a higher standard of quality because:

Actually properly research what is needed for this implementation. Until someone actually decides to the hard work this section should be dedicated to the stuff that is most definietly needed for this implementation to work. And when thats done this notice should be deleted.

Lamba War's source code Reference project : Source 2013MP deferred this project uses the older Alien swarm deferred's version but it still should give us some idea what needs to be changed.
