Look at the pixmap_browser demo in the test folder. See how it uses
img->copy(...) to resize the image.
That is the easiest way, although the resizing method used is not the
most advanced, so may give less than ideal results at very large or very
small scales.
If you need better scaling, you probably would need to use some more
sophisticated image processing techniques to scale the image.
