// Notas acerca de Posicionamiento //
// ------------------------------- //
// Tipicamente Xpos y Ypos indican el poscicionamiento del floater en referencia al FunctionName.
// Para posicionar el floater en una posicion arbitraria, es necesario aņadir la variable
// freeMove=yes bajo params. Esto hace que no sea en referencia a FunctionName si no en donde
// Xpos y Ypos indiquen.
