  Split the SamplerState struct into SamplerState and TextureState.
  
  SamplerState is now only the members that are overridden by a sampler
  object, this makes it easy to update those specific members.
  
  Opted for getters and setters for each member in Texture and Sampler
  because it will be required to enable dirty bits for these states.
  
  Added maxAnisotropy to the SamplerState instead of texture state.  The
  sampler objects extension mentions it should be there.
