extends SceneTree
## Outil de developpement : charge une scene, attend quelques images puis
## enregistre le rendu en PNG. Usage (fenetre reelle, pas --headless) :
##   godot --path . --resolution 1152x648 -s res://tools/screenshot.gd -- \
##       res://scenes/world/world_map.tscn out.png [CE1|CE2|CM1|CM2] [mission_id]
## Cree un profil temporaire pour que les scenes qui lisent la progression
## fonctionnent, puis le supprime.
