* Bonus Asset - Extensible Power-Up System
* 
* The Bonus asset supports a wide range of features and properties to enable rich gameplay and power-up mechanics.
* Below are some of the key properties and extensibility points for the Bonus asset:
* 
* 1. duration: (Number) - Duration of the bonus effect in frames or seconds.
*    Example: duration: 300 // lasts for 5 seconds at 60fps
* 
* 2. stackable: (Boolean) - Whether the bonus effect can be stacked or only the duration is extended.
*    Example: stackable: true
* 
* 3. isActive: (Boolean) - Indicates if the bonus is currently active.
*    Example: isActive: true
* 
* 4. effect: (String) - Visual effect or animation type when the bonus is picked up or active.
*    Example: effect: 'glow', effect: 'pulse'
* 
* 5. scoreMultiplier: (Number) - Multiplier applied to score when the bonus is active.
*    Example: scoreMultiplier: 2
* 
* 6. target: (String) - The target of the bonus effect (e.g., 'player', 'allEnemies').
*    Example: target: 'player'
* 
* 7. onActivate: (Function) - Custom behavior function triggered when the bonus is activated.
*    Example: onActivate: function () { /* custom logic *\/ }
* 
* 8. Visual Properties: (Object) - Customization for appearance such as icon, color, animation speed.
*    Example: icon: 'star', color: 0xff00ff
* 
* 9. usageLimit: (Number) - How many times the bonus can be used.
*    Example: usageLimit: 3
* 
* 10. cooldown: (Number) - Cooldown period before the bonus can be picked up again.
*     Example: cooldown: 600 // in frames
* 
* 11. type: (String) - The type of bonus (e.g., 'speed', 'shield', 'invisible', 'score').
*     Example: type: 'shield'
* 
* 12. sound: (String) - Sound effect to play when the bonus is picked up or active.
*     Example: sound: 'bonus_pickup'
* 
* 13. spawnCondition: (String) - Condition for spawning the bonus.
*     Example: spawnCondition: 'score>1000'
* 
* 14. area: (Object) - Area of effect for the bonus.
*     Example: area: { x: 100, y: 200, radius: 300 }
* 
* 15. isNegative: (Boolean) - Whether the bonus is a negative (penalty) effect.
*     Example: isNegative: true
* 
* The Bonus class can be extended or configured with these properties to create a variety of power-ups,
* such as temporary shields, score multipliers, speed boosts, area effects, and more.
* This system allows for both positive and negative bonuses, visual and audio feedback, and custom behaviors.
