Added another color attachment to the current FBO. Need to test and fix it now.
For some reason, the binding of the SSAO attachment point (GL_COLOR_ATTACHMENT3) which is GL_TEXTURE6 (6 to the shader) is returning 0. Must look into that.
The third pass shader is getting nothing. Not one of the uniforms are right. Must fix this.
Forgot to bind the third pass shader.
Must think this third pass insertion through.
Added a link to a german website with a lot of tutorials.
Third pass is showing the image at least.
Blur is complete, but it did not help.
Finished the basic implementation.
