Bye, TGGC (Demo or Die)

Gehts nicht genauer, was du wissen willst? ^^
Is halt ein kleines WinAPI-Programm, dass OpenGL benutzt, und das noch nicht mal besonders gut.^^
Ratefrage: Ich las da TBitmap, tippe also mal auf Borland C++ Builder^^

Was TGGC damit sagen will: Niemand, der keinen persönlichen Vorteil darin erkennen kann, den Code für dich zu verstehen, ließt sich das hier durch. Und solche Altruisten gibt es nur sehr selten.
