NAME
       gl_WorkGroupSize - contains the size of the workgroup operated on by a compute shader


DECLARATION
       const uvec3 gl_WorkGroupSize ;.SH "DESCRIPTION"

       In the compute language, gl_WorkGroupSize contains the size of a workgroup declared by a
       compute shader. The size of the work group in the X, Y, and Z dimensions is stored in the
       x, y, and z components of gl_WorkGroupSize. The values stored in gl_WorkGroupSize match
       those specified in the required local_size_x, local_size_y, and local_size_z layout
       qualifiers for the current shader. This value is constant so that it can be used to size
       arrays of memory that can be shared within the local work group.
