    "DESCRIPTION" 
 In the compute language,  gl_LocalInvocationIndex  is a
    derived input variable containing the 1-dimensional linearized index of the
    work invocation within the work group that the current shader is executing
    on. The value of  gl_LocalInvocationIndex  is equal to
     gl_LocalInvocationID.z  *  gl_WorkGroupSize.x  *
     gl_WorkGroupSize.y  +  gl_LocalInvocationID.y  *
     gl_WorkGroupSize.x  +  gl_LocalInvocationID.x .
