Subject: glsl/cs: Initialize gl_GlobalInvocationID in main()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We initialize gl_GlobalInvocationID based on the extension spec
formula:

    gl_GlobalInvocationID =
        gl_WorkGroupID * gl_WorkGroupSize + gl_LocalInvocationID
