fix: els globos tenien un parell de setters mal asignats per culpa de buscar y reemplazar

fix: els globos verds s'inicialitzaven amb vy = 0 per gastar abs en lloc de fabs
fix: corregit un bug milenari que de sempre havia creat els balloons verds al popar al pare amb la meitat de velocitat en y. Lo que jo no se es com anava res. Supose que ara el joc serà un poc mes xungo. Quan rebotaven en el piso ja se'ls posava la velocitat bona (crec)

+    Esta clase es la encargada de dibujar el fondo que aparece durante la sección
+    jugable.
+
+    Utiliza una textura donde compone la imagen y luego tiene una textura superior
+    rellena de un color sólido cuya opacidad se puede modificar.
+
+    El objeto tiene un tamaño total definido en la variable "rect". En principio este
+    tamaño coincide con el tamaño de la ventana o resolución del juego, pero se pinta
+    solo el rectangulo definido en srcRect en la posición de la pantalla definida en
+    dstRect.
+
+    Ambos rectangulos han de coincidir en tamaño y por definición, el punto comun es el inferior derecho el rectangulo.
+
+    Utiliza varios métodos para definir su comportamiento:
+        - setCloudsSpeed(float value)
+          Velocidad a la que se desplazan las nubes cada frame
+
+        - setGradientNumber(int value)
+          Escoge el índice de la textura de fondo a usar (el color del cielo)
+
+        - setTransition(float value)
+          Porcentaje (entre 0.0f (textura actual) y 1.0f (textura siguiente)) para mostrar entre la textura de fondo actual y la siguiente
+
+        - setSrcRect(SDL_Rect value)
+          Rectangulo de la textura de fondo que se desea mostrar
+
+        - setDstRecr(SDL_Rect value)
+          Rectangulo de destino donde se mostrará el rectángulo antrior. Automaticamente modifica srcRect para coincidor en tamaño con el destino.
+
+        - setColor(Color color)
+          Establece el color de la textura de superposición
