User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20160518030234

Steps to reproduce:

On current Firefox Nightly Build 49.0a1 (2016-05-18) and previous versions:
Created a vertex shader which attempts to access the gl_VertexID variable.

(This variable is part of the OpenGLES 3.0 spec which WebGL 2.0 is based upon: https://www.khronos.org/files/opengles3-quick-reference-card.pdf on Page #5)


Actual results:

The vertex shader failed to compile with the following error:
'gl_VertexID' : undeclared identifier


Expected results:

The vertex shader should have compiled.

This isn't implemented in the version of ANGLE we have in-tree at the moment. Will probably be fixed on next ANGLE update.
