Controlling sun with a window InGame
In commit #adc0925d I have put the sun and a WorldEnvironment in the basic_setup scene, as it is linked to it and can be changed if we use another test scene. I think it would be useful to have a way to tweak the sunlight directly when in game, to check some visual effects.
We should be able to change at least the following sunlight parameters :
- its rotations for its day cycle
- its Light3D parameters for color and Energy (mainly)
