Handle failure of Windows XP theme painting functions for PE_FrameWindow.
QWindowsXPStylePrivate::buffer() can fail due to CreateDIBSection()
failing for large sizes. Introduce a bool return for the
QWindowsXPStylePrivate::drawBackground() helpers and fall back to
QWindowsStyle:::drawPrimitive() should that happen for PE_FrameWindow
in QWindowsXPStyle::drawPrimitive().
