 * ===========================================================================
 * 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 < -----

 * ---> 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.
