Tabs with corner widgets are drawn incorrectly in document mode on Mac.

While drawing the tabbar frame, mac style needs the QTabBar pointer to
calculate the correct size.
Since the QTabWidget also uses the PE_FrameTabBarBase to draw background
of the corner widgets, the mac style has to use position passed with the
style option. This only works with horizontal tabs.
