  Free OSWindow and EGLWindow through helpers.
  
  This cleans up any potential problems with allocating and freeing
  resources in different shared objects or DLLs. Previously we were
  using a dynamically linked allocation function and then calling
  the standard delete function.
  
  Also adds a base class helper for EGLWindow. Will base the WGL
  Window class on this.
  
  Needed for running ANGLE tests against native drivers.
