 Bugs
 ====
- * bad sphere/box transmisivity
-   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.
+ * (none known)
 
 Future Plans
 ============
  * changing main ray tracing algoritm to more flexible architecture with a Sampler object:
   - enhance Sampler to support subsampling
-  - rewrite pthreads
  * namespace
  * kd-tree:
    - optimize structures
@@ -23,10 +19,6 @@
  * implement efficient AABB-ray intersection using Plucker coordinates
  * generalization: Camera "shader" (ray generator), surface shader and maybe light & background shaders
 
-Performance Weak Points
-=======================
- * Raytracer::render -- allocating and deallocating every sample
