+      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). -->
