-<!--<indexentry primary "pass_through">--->
-<p>The keyword <code>pass_through</code> causes photons to pass through the
-object <strong>unaffected</strong> on their way to a target object. Once a
-photon hits the target object, it will ignore the <code>pass_through</code>
-flag. This is basically a photon version of the <code>no_shadow</code>
-keyword. If you use the <code>no_shadow</code> keyword, the object will be tagged as
-<code>pass_through</code> automatically. You can then turn off
-<code>pass_through</code> if necessary by simply using <code>photons {
-pass_through off }</code>.</p>
-[clipka - Removed the mentioning of media still collecting photons, as it was wrong (fortunately) even for 3.6: on their way to their target, photons are ''never'' collected by other objects, whether they are pass_through or otherwise.]
