Replaced matrix related FFP code with explicit matrix calculations. The modelview matrices now get uploaded at a single point via glLoadMatrix4 rather than using the GL1 matrix stack. In the GL2 variant this will become a uniform upload.

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

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