[IonutCava]
- Prev Frame attachment system removed from RenderTargets
— Concept too high level for RT. Moved prev depth buffer to GFX class
- Other small optimizations.

[IonutCava]
- Fixed viewport alignment issue
- Added per-player RenderTargets (added index support to GFXRTPool)
- Initial implementation of per-player cameras
— Removed defaultCamera
— Scenes now use a baseCamera as a template for new player cameras

- Added support for the Arena Allocator by Mamasha Knows (http://www.codeproject.com/Articles/44850/Arena-Allocator-DTOR-and-Embedded-Preallocated-Buf)
— Used for GFX Related objects: Textures, shaders, etc

- Improve the CommandBuffer system to include the notion of a RenderPass /RenderSubPass with output render target info stored in them (not used yet)

- Prepare velocity map calculation (later used for temporal AA and motion blur):
— Add a previous depth buffer render target that blits the main depth buffer at the end of the frame
— Add a new render target to the screen FBO: velocity map
- Store normals as RG instead of RGB and pack/unpack in shaders. (compute >>>> bandwith)
- Rename Forward+ renderer to something more descriptive

(Requires deletion of all parsed & cached data)

[IonutCava]
- Clean up camera class:
— Remove “reflection” specific code and add a generic “reflect” method to allow the calling code to handle camera placements and reflections. This got rid of the “reflectionPlane” member in the RenderParams struct
— Remove some member variables and replace them with on-demand computed variables on the stack.
— Add a “destroyCamera” call to the CameraManager to allow better resource cleanup when needed
- Prepare a rendering system overhaul:
— Add dual screen render targets: current frame and previous frame. Used for future features such as TXAA and Motion Blur.
— Prepare code for an implementation similar to the Doom (2016) system: http://www.adriancourreges.com/blog/2016/09/09/doom-2016-graphics-study/ (the code was already going in that direction)

[IonutCava]
- Added initial environment mapping code:
— Allow adding, per scene, of multiple environment probes that generate cube map reflections
— Support 2 types of probes: infinite (such as sky only probes) and local. Local probes use an AABB that will later be used for parallax correction
— Probes are held in a scene specific pool, can be updated at different rates and their results can be passed on to materials (if materials don’t need specific reflection systems such as for water or mirrors)
- ToDo:
— Blend between probes (currently, only the closes one is selected)
— Reduce VRAM usage
— Set as fallback for screen space reflections

[IonutCava]
- Added a render target pool:
— All render targets are now allocated (and tracked) by the GFXDevice.
— Allocation routines return a slim RenderTargetHandle object that will be used later on in draw commands.

- Added a refraction render pass that will handle translucent objects that need refracted textures instead of clear transparency
— Both reflective nodes and refractive nodes are not gathered properly at this point

- All API specific objects (buffers, textures, etc) are now initialized in the GFXDevice class (see GFXDeviceObjects.cpp)
— This allowed for the slimming of the RenderAPIWrapper interface

- Improved ENABLE_GPU_VALIDATION macro utilization:
— It enabled shadow map split plane debugging
— It bypasses loading shaders from text cache
