  Proliferate gl::Context everywhere.
  
  This gives the D3D back-end access to the GL state almost anywhere.
  This uses the onDestroy hook for Textures to push errors up from
  destructors, although they still don't quite make it to the Context.
  
  There are places, such as in EGL object (Context/Surface) destruction,
  where we end up calling through to GL implementation internals without
  having access to a gl::Context. We handle this via a proxy Context
  to a Display, basically a null context, that has access to impl-side
  state like the Renderer pointer if necessary. It does not have access
  to the normal GL state.
  
  Also Pass gl::Context to RefCountObject::release(). Since we're using
  destroy() methods now, we should not ever call the destructor directly.
