    Inside-out transition is ignored as every second intersection is ignored to avoid duplicit
    intersect points. This solution should be replaced by moving ray origin a little forward, which
    should work as well and without side-effects.

 Future Plans
 ============
  * changing main ray tracing algoritm to more flexible architecture with a Sampler object:
-  - update all demos for new Sampler/Camera architecture
-  - enhance Sampler to support oversampling and subsampling as before

   - rewrite pthreads

+Performance Weak Points
