    11031103<li>_L - choose LOD from VADDR from last register, after other components.</li>
    11041104<li>_C - compare (by using z-compare function from sampler) fetched data from image
    1105 (first component of pixel) with Z-COMP component from VADDR.</li>
     1105(first component of pixel) with Z-COMP component from VADDR. Working only with
     1106floating point images.</li>
    11061107<li>_O - apply offset to image's address (add X, Y and Z offset to X, Y and Z coordinates).</li>
