use opacity to indicate thawing. not totally happy w/ effect, but argument was made to indicate some progress towards thaw. drop "exit" since it really wasn't helpful, and not rendering tags, was more annoying than fun.

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

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