<!-- Dynamic bitfield containing WorkGroupSize.xyz, NumWorkGroups.xyz
The number of bits allocated for each number is based on the *_shift
fields. For example, workgroups_y_shift gives the bit that
gl_NumWorkGroups.y starts at, and workgroups_z_shift gives the bit
that gl_NumWorkGroups.z starts at (and therefore one after the bit
that gl_NumWorkGroups.y ends at). The actual value for each
is one more than the stored value, since if any of the values
are zero, then there would be no invocations (and hence no job). -->
