Start piano higher (piano on maps that matched land_height was really weird before). Experiment w/ trying to make birdy shrink into distance to avoid odd birdy vanishes if tracking it.

#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}
