 * +++ MOG - Menu Background (v1.2) +++
 * By Moghunter 
 * https://atelierrgss.wordpress.com/
 * =============================================================================
 * O plugin permite mudar a imagem de fundo do menu.
 * É possivel ativar uma imagem diferente para cada cena ou desativar a imagem
 * de fundo em cenas especificas.
 * =============================================================================
 * As imagens do background deverão ficar na pasta /img/pictures/
 * =============================================================================
 * No caso da opção Unique Backgrounds estiver ativada cada imagem de fundo 
 * deverá seguir essa nomeação.
 *
 * SCENE_NAME + _back.png
 *
 * Exemplo.
 *
 * Scene_Menu_back.png
 * Scene_Item_back.png
 * Scene_Skill_back.png
 * etc...
 *
 * =============================================================================
 * PLUGIN COMMAND
 * =============================================================================
 * Para mudar a imagem de fundo durante o jogo use o comando abaixo.
 *
 * backgroundName : FILE_NAME
 * 
 * =============================================================================
 * HISTÓRICO
 * =============================================================================  
 * v1.2 - Compatibilidade com MOG_PictureGalery. 
 * v1.1 - Melhoria na codificação.
