Reviewed by Alan Baradlay.
When the input was set to a specific value, internally the
thumb was moved to the correct position, which marked as
dirty both areas for the previous and new positions.
However, nothing else was marked dirty, including the track
itself, so if the thumb moved from (say) 0% to 100%, some
of the middle part may not have been marked as dirty.
On iOS, the track has a different color on each side of
the thumb position, so the non-dirty part was staying the
same color as it was before.
The fix is to ensure that the track gets repainted, so that
any needed color change happens along its length.
