-##
-# A scene is a non-linear graph that assembles layers together to tell a story.
-# Layers are folders with appropriately named files (see below). You can group 
-# layers and control them together or just set their values individually.
-#
-# Examples:
-#
-# * A city scene that changes with the time of day and the weather conditions.
-# * A traffic map that shows red lines on streets that are crowded and green on free-flowing ones.
-#
-# Usage:
-# 
-#  g = Gruff::Scene.new("500x100", "artwork/city_scene")
-#  g.layers = %w(background haze sky clouds)
-#  g.weather_group = %w(clouds)
-#  g.time_group = %w(background sky)
-#  g.weather = "cloudy"
-#  g.time = Time.now
-#  g.haze = true
-#  g.write "hazy_daytime_city_scene.png"
-#
-#
-#
-# If there is a file named 'default.png', it will be selected (unless other values are provided to override it).
