Here, fillRect wants a QBrush and we passes a WebCore::Color. So compiler needs
to find QColor to convert from WebCore::Color to QBrush, which is different
situation from IntRect to QRect (no intermediate class needed).
(In Qt 4.5, fillRect takes a QColor, so it works fine?)
I'm not sure, but this is the explanation?
