Improve ProgressBar and Slider styleeel_5.1.0eel_5.0.3eel_5.0.2eel_5.0.1eel_5.0.0eel/5.1.0eel/5.0.3eel/5.0.2eel/5.0.1eel/5.0.05.1.05.0.35.0.25.0.15.0.0eel

The position of stop 1.0 was set to the positoin of "value" in both 
controls. Due to this, gradiation was changed/re-drawn whenever value
was changed.
This commit sets the position of stop 1.0 to the end of the control. 
Now gradiation itself is fixed, not changed by its value.
