49 HACK: for scrollbars in case of thumb rect, page up and page down rect we
50 abuse the HitTestNativeControl interface. All theming engines but aqua
51 are actually able to draw the thumb according to our internal representation.
52 However aqua draws a little outside. The canonical way would be to enhance the
53 HitTestNativeControl passing a ScrollbarValue additionally so all necessary
54 information is available in the call.
55 .
56 However since there is only this one small exception we will deviate a little and
57 instead pass the respective rect as control region to allow for a small correction.
58
59 So all places using HitTestNativeControl on PART_THUMB_HORZ, PART_THUMB_VERT,
60 PART_TRACK_HORZ_LEFT, PART_TRACK_HORZ_RIGHT, PART_TRACK_VERT_UPPER, PART_TRACK_VERT_LOWER
61 do not use the control rectangle as region but the actuall part rectangle, making
62 only small deviations feasible.
