    \class QWindowsXPStyle
    \brief The QWindowsXPStyle class provides a Microsoft WindowsXP-like look and feel.

    \ingroup appearance

    \warning This style is only available on the Windows XP platform
    because it makes use of Windows XP's style engine.

    Most of the functions are documented in the base classes
    QWindowsStyle, QCommonStyle, and QStyle, but the
    QWindowsXPStyle overloads of drawComplexControl(), drawControl(),
    drawControlMask(), drawPrimitive(), subControlRect(), and
    sizeFromContents(), are documented here.

    Dumps a portion of the full native DIB section double buffer.
    The DIB section double buffer is only used when doing special
    transformations to the theme part, or when the real double
    buffer in the paintengine does not have an HDC we may use
    directly.
    Since we cannot rely on the pixel data we get from Microsoft
    when drawing into the DIB section, we use this function to
    see the actual data we got, and can determin the appropriate
    action.
