    HACK: for scrollbars in case of thumb rect, page up and page down rect we
    abuse the HitTestNativeScrollbar interface. All theming engines but aqua
    are actually able to draw the thumb according to our internal representation.
    However aqua draws a little outside. The canonical way would be to enhance the
    HitTestNativeScrollbar passing a ScrollbarValue additionally so all necessary
    information is available in the call.
    .
    However since there is only this one small exception we will deviate a little and
    instead pass the respective rect as control region to allow for a small correction.

    So all places using HitTestNativeScrollbar on ControlPart::ThumbHorz, ControlPart::ThumbVert,
    ControlPart::TrackHorzLeft, ControlPart::TrackHorzRight, ControlPart::TrackVertUpper, ControlPart::TrackVertLower
    do not use the control rectangle as region but the actual part rectangle, making
    only small deviations feasible.
