- Camera looses its orientation when changing render quality.
- Choosing New in Scene menu makes the daytime at 0.0.
- All noises should use the same entropy pool (saved separately), and avoid reallocs.
- Implement light multi-sampling (mainly for skydome).
- Implement scaling and scrolling on previews.
