(experimental) make the mysterious borders around land/hats/etc that appear on zoom vanish
note: not applied to everything yet
note: I'll probably merge the two functions that do the same thing (one for 1darray, one for 2darray representation of pixels) into a single function
#include <QtGui/QApplication>
#include "mainwindow.h"
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
}
