Title: GF-61229: At the end of video stream, the knob indicate unexpected position

WHEN current time is bigger than duration, the knob deviate from slider.
Because, Progress and BgProgress values are clamped in moon.ProgressBar, but the knob position is not clamped.
So, I have added clamping inValue for knob position.
