secrets, a sign, a reason

Let us start with a comparison (longer is better):

If you see the my latest graphics example: 50% scaling of (A)RGB32 image, you will find a 10x faster way (compared to QImage::scaled() function) to downscale an image to the half its original size, of course with (approximately) the same visual quality as when you use Qt::SmoothTransformation.

For the readers who also did listened to my Qt Developer Days graphics talk, you can have an idea why I make so much fuss just for image halfscaling 🙂 Bear with me and we will reach that point.
