  Expose ViewID_OVR impostor in the fragment shader
  
  The OVR_multiview specification states that gl_ViewID_OVR is visible
  at each pipeline stage. Previously to this patch the ViewID_OVR
  impostor was declared only in the vertex shader and occurrences of
  gl_ViewID_OVR in the fragment shader were not being handled. The
  patch addresses the issue by declaring the ViewID_OVR variable as
  a vertex output in the vertex shader and as a fragment input
  in the fragment shader.
