    Hash : 2f6ddf31
    Message : Allow double underscore in macro names Double underscore is allowed according to GLSL ES 3.10, and based on Khronos discussions the intent is that this should also apply to older specs. The dEQP tests also check this, and WebGL tests that check the opposite were recently removed. The error is changed into a warning.
