Created class GBuffer
All set up for first test.
GBuffer writing works! Made some minor corrections.
Depth is dumpable
GBuffer::bindAsSource modified. Binds buffers as textures
Ready for ambient-pass test#1
SetUp for Dir lights finished
WS-Coords saving and DirLightPass works
Exception catch. No dirlight caused black screen
Reordered Rendering. Added Scene::_fullscreenVbo
Tweak complete and some other things corrected
changed diffusePass to lightpass (do everything at once)
RenderTexture can be set to specific color attachments
Last commit reverted. that is dumb. new attempt...
Idea: addColorAttachment. Rework the additional textures
Updated doc

Cleaned up Repo
