== TO DO ==

• Use a better random generator
• Use gamma 2.2 for float to integer conversion
• Fix firefly
• Fix anti-firefly (some pixel remain dark). It comes from NAN value.
• Implement Russian Roulette termination
• Importance sample at least according to "cos(theta)".
• Fix black light bug (because the first ray from camera does not sample the light)
• Next event estimation
• Remove useless SFML dependencies (audio, network, ...)
• Add other BSDF (reflection, refraction)
• Improve variance:
  • try stratified sampling (http://www.rickdebruijne.nl/data/pathtracer/literature_research.pdf)
  • Review current next event estimation implementation from Multiple Importance Sampling point of view
• Add tone mapping
• Load object from files
• Bidirectional Path-tracing
• Profile and optimize code
