◆ SetWorkgroupSize()

ComputePipelineDescriptor & impeller::ComputePipelineDescriptor::SetWorkgroupSize ( std::array< uint32_t, 3 >  size)

Set the workgroup (threadgroup) size declared by the shader. 

        A dimension of 0 is sized by a specialization constant and
        resolved by the backend at dispatch (for example, to the
        device maximum).
