- Split Resource class into Resource and CachedResource
— CachedResource is the only resource held in a ResourceCache and loaded from a ResourceDescriptor
— CachedResource is mapped by its creation descriptor’s hash value, instead of the resource name
-— Multiple cached resources can now exist with the same name if the have different properties, for example.

- Singleton elimination update Part I: get it to compile
— The following classes are no longer Singletons: GFXDevice, GL_API, DX_API, SFXWrapper, FmodWrapper, SDLWrapper, ALWrapper, PXDevice, InputInterface, RenderPassManager, SceneManager and ResourceManager;
— Refactor system to a Context / Component based implementation (Pass relevant context to objects: e.g. GFXDevice object to Textures, GUI to GUIElements, etc)
— Make devices and managers components of the kernel
— Allow multiple Resource caches to co-exist. This may prove useful for later when a more fragmented memory model is need (per frame / per scene / global caches / etc)

  • next steps: part II – cleanup/refactor new code, part III – optimise code, part IV – remove remaining Singletons (e.g. Application, ParamHandler, FrameListenerManager, Recast, PostFX and DebugInterface)

[IonutCava]
- Massive rewrite of the resource system:
— ResourceCache now uses a map of weak pointers and passes shared pointers to the call point of CreateResource
— RemoveResource is no longer needed, but resource based smart pointers use a custom deleter that calls unload()
— Keep a shared_ptr of the resource in the entity that needs it and pass shared_ptr references from getter methods
-— All of this removed the need for calls to RemoveResource, REGISTER_TRACKED_DEPENDENCY and UNREGISTER_TRACKED_DEPENDENCY reducing the number of mutex locks and atomic exchanges
- Singleton cleanup:
— Removed ShaderManager singleton and merged it’s data and responsibilities in static methods in both ShaderProgram and Shader classes.
Explanation: Due to the complex interdependency chains in the system, copying, updating, tracking the cache in a thread safe way became a lot more slower than a straight forward smart pointer based implementation. (e.g. scene graph nodes have 3d objects and material instances, 3d objects have materials, materials have textures and shaders, etc)

[IonutCava]
- Resource system cleanup:
— Resource name and resource file location (if any) is now passed only via explicit constructors! (ResourceDescriptors already contain this data, so why use setters?)
- Fix a bug with ortho projection matrix calculation (set m[3][3] to 1. this was skipped when the identity() call was changed to zero() in the ortho() function)
— This also fixed text rendering
