 * =============================================================================
 * Adiciona um cursor animado no menu.
 * Será necessário o arquivo Menu_Cursor.png gravado na pasta. (img/system/)
 *
 * =============================================================================
 * HISTÓTICO
 * =============================================================================
 * (v1.4) - Correção da velocidade do cursor na cena de titulo. 
 * (v1.3) - Correção de na atualização na posição do Index quando os comandos
 *          ultrapassam o tamanho da janela.
 *        - Melhoria na compatibilidade de plugins.
 * (v1.2) - Melhoria no sistema de rolamento do mouse. 
 * (v1.1) - Correção do glitch de não ocultar o cursor durante o fade da cena.
 *        - Melhoria da animação inicial do cursor.
