What is the use of ITK, ITCL and TIX within OpenCascade. There is a clear reference to these 3 libraries in the ros/env.ksh file but I would like to know if they are essential or not to OpenCascade. I am in the process of writing an ebuild of OpenCascade for Gentoo and I need to determine what is really needed and what is not.
ITK, ITCL and TIX are on my list. However, I am not really sure they should be there...
