- Added debug scope (GL’s debug group) commands
- More bug fixes and optimizations

[Ionut]
- Cleanup Text rendering and text related structs
- Add labels to DebugViews

[Ionut]
- Rework RenderTarget binding. Now access is only available via the GFXRTPool
- Split RenderPassManager::doCustomPass into multiple steps for easier debugging and cleaner code
- Other small code cleanups

- Optimise static casts

[IonutCava]
- Rename to_XNN and to_const_XNN functions to reflect the target data type they are converting to.
- Cleanup Angle namespace and remove all “inDegrees” parameters from rotation functions. Use aliases to differentiate between Degree and Radian parameters.
- Profile guided optimizations.

[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
