Alan,
It's optional since it doesn't necessarily work on all supported OpenGL
drivers -- at least that used to be the case in OpenGL1 days. I need to
check if that's still true.

To specify further, I get the same results on my Mac. I do see the LIC on the
surface inside that hole. I was refering to the outside part of the cylinder.
But looking more closely at the data, I see that the velocity is 0 there, so
that would explain why the LIC is not showing anything there.
