 * Adiciona uma bússola indicando o destino a ser seguido.
 * É necessário ter as seguintes imagens gravadas na pasta /img/system/
 *
 * Compass_A.png
 * Compass_B.png
 * Compass_C.png
 *
 * ===========================================================================
 * Para definir o evento que representa o destino basta colocar
 * este comentário.
 *
 * <Destination>
 *
 * ===========================================================================
 * Para ocultar ou mostrar o compasso use este código através do PLUGIN COMMAND.
 *
 * hide_compass
 *
 * show_compass
 *
 * ===========================================================================
 * Para forçar um evento de destino use o comando abaixo.
 * (NOTA - Esse comando é apenas para efeito temporário, ao usar o teleport
 *         o evento volta ao estado normal.)
 *
 * compass_event_id : EVENT_ID
 *
 * ===========================================================================
 * HISTÓRICO
 * ===========================================================================
 * v1.6 - Melhoria da codificação e na compatibilidade de plugins.
 * v1.5 - Melhoria da codificação e na compatibilidade de plugins.
 * v1.4 - Compatibilidade com o Chrono Engine
 * v1.3 - Correção do glitch de piscar a hud.
 * v1.2 - Correção do efeito blinking da bussola durante os dialogos.
 * v1.1 - Correção do crash ao apagar (Erase) o evento do mapa.
 *      - Correção do efeito smart Fade.
 *      - Correção de não desligar o destino após ativar uma página em branco.
