Scale icons returned by QIcon::fromTheme.
The icon engine behind icons that are loaded from QIcon::fromTheme does
not scale any pixmaps that it returns. When using an icon theme with an
incomplete set of icons (for example, only a "128x128" folder),
QIcon::pixmap will always return 128x128 pixmaps even if you ask for
one of size 22x22.
This is contrary to the QIcon::pixmap documentation that says "The
pixmap might be smaller than requested, but never larger."
This patch uses the same code that is in the main QIcon class in the
PixmapEntry QIconLoaderEngineEntry to scale pixmaps if they are too big.
