The y-coordinate of the top of the scrollbar track as it is rendered in the display (excluding the scroll buttons at the top and bottom).

pixel position = (scrollbar coordinate * TrackSpanHeight / (Map.Maximum + Map.ViewportSize)) + TrackSpanTopscrollbar coordinate = (pixel position - TrackSpanTop) * (Map.Maximum + Map.ViewportSize) / TrackSpanHeight.
