  Set __VERSION__ macro when the #version directive is parsed
  
  __VERSION__ macro needs to be set to 300 when #version 300 es is on the
  first line of the shader, since section 3.4 of ESSL 3.00.4 spec mentions
  that the value of __VERSION__ should match the shading language being
  parsed. The value from parsing the version directive replaces the default
  value 100.
