 byte[] bitmap;
 bitmap = LoadBitMapFromFile("worldroadmap.bmp");
 GammaAdjust(bitmap, 0.20);
 Render(device, bitmap);

If the 'GammaAdjust' routine changed the pointer then 'Render' routine
would not display the adjusted bitmap. 

So I would like to tell the compiler that 'GammaAdjust' is not allowed to
change the pointer and thus if (at compile time) it does so the compiler
should tell me of the error.
