  Add a ContextImpl class.
  
  This class can contain impl-specific functionality for a Context.
  This will eventually replace the Renderer class, and we can then
  start passing around a gl::Context instead of gl::ContextState.
  
  In D3D11, the ContextImpl could hold a DeferredContext, which would
  enable multi-thread rendering. In GL, we can implement non-virtual
  (native) Contexts. In Vulkan it might store the logical device.
