Use libjpeg's builtin scaler for implementing setScaledSize()
The libjpeg library has builtin support for scaling to 1/2, 1/4, and 1/8
the original size very quickly. Use this in the implementation of
setScaledSize() to get close to the desired size and then scale
with QImageSmoothScaler the rest of the way.
