 * +++ MOG - Picture Effects (v1.4) +++
 * By Moghunter 
 * https://atelierrgss.wordpress.com/
 * =============================================================================
 * Adiciona novas funções no sistema de mostrar imagens.
 * =============================================================================
 * UTILIZAÇÃO.
 * =============================================================================
 * Utilize os comandos através do Plugin Command.
 *
 * =============================================================================
 * * POSITIONS * 
 * =============================================================================
 * --- > Posição da imagem no player. < ----
 *
 * picture_player_position : PICTURE_ID
 *
 * --- > Posição da imagem no evento. < ----
 *
 * picture_event_position : PICTURE_ID : EVENT_ID
 *
 * --- > Posição fixa no mapa. < ----
 *
 * picture_map_position : PICTURE_ID
 * 
 *
 * (NOTA - A função MOVE não funciona nos efeitos de Posição.)
 *
 * =============================================================================
 * * EFFECTS * 
 * ============================================================================= 
 * ---> Efeito Respirar < -----
 * 
 * pic_breath : PICTURE ID : true : Power : Speed
 *
 * ---> Efeito Flutuar < -----
 * 
 * pic_float : PICTURE ID : true
 *
 * ---> Efeito Tremer < -----
 * 
 * pic_shake : PICTURE ID : true : Power
 *
 * ---> Efeito Tremer 2 < -----
 * 
 * pic_shake2 : PICTURE ID : true : Power
 *
 * ---> Efeito Smooth < -----
 * 
 * pic_smooth : PICTURE ID : true : Power : Speed
 * 
 * =============================================================================
 * * ANIMATED * 
 * ============================================================================= 
 * 
 * picture_animated : PICTURE_ID : NUMBER_OF_FRAMES : ANIMATION_SPEED
 *
 * (NOTA - A largura da imagem é dividida pelo numero de frames.)
 *
 *
 * =============================================================================
 * * HISTÓRICO * 
 * =============================================================================
 * (1.4) - Compatibilidade com Rpg Maker MV 1.6+
 * (1.3) - Adicionado o efeito Smooth.
 *       - Adicionado as opções de definir o poder e velocidade dos efeitos.
 * (1.2) - Adicionado a função de tremer no modo 2.
