  Create a default framebuffer per surface/context pair on MakeCurrent.
  
  Sharing a gl::Framebuffer object between multiple contexts causes problems if
  contexts are not virtualized because the native framebuffer objects are not
  shared between these contexts.  The FramebufferImpl created should be the glue
  that binds a specific context to a specific surface.
  
  Update the SurfaceImpl implementations to re-create the framebuffer
  object before passing it to FramebufferGL.  No backing resources will be
  re-created.
