  Select viewport index in the GLSL/ESSL vertex shader
  
  The patch enables viewport selection for multiview rendering in the
  GLSL/ESSL vertex shader through the use of the GL_NV_viewport_array2
  extension. The AST is modified only for GLSL and ESSL to include the
  viewport selection expression after ViewID_OVR's initialization.
