<pre>Web Inspector: Opacity slider thumb sometimes goes past the bar in Visual Styles sidebar
https://bugs.webkit.org/show_bug.cgi?id=154497

Patch by Devin Rousso &lt;dcrousso+webkit@gmail.com&gt; on 2016-02-20
Reviewed by Timothy Hatcher.

Since WebInspector.Slider uses CSS transforms to move the slider knob
along the track, if the width of the track changes then the position
of the knob would stay the same since it was translated instead of
adjusting its position relative to the new width.

* UserInterface/Views/Slider.js:
(WebInspector.Slider.prototype.recalculateKnobX):
Resets the maxX value to 0 to ensure that a new maxX is calculated with
the current width.

* UserInterface/Views/VisualStyleCommaSeparatedKeywordEditor.js:
(WebInspector.VisualStyleCommaSeparatedKeywordEditor.prototype.set specifiedWidth): Deleted.
(WebInspector.VisualStyleCommaSeparatedKeywordEditor.prototype.recalculateWidth):

* UserInterface/Views/VisualStyleDetailsPanel.js:
(WebInspector.VisualStyleDetailsPanel.prototype.widthDidChange):
(WebInspector.VisualStyleDetailsPanel.prototype._updateProperties):
(WebInspector.VisualStyleDetailsPanel.prototype._populateDisplaySection):

* UserInterface/Views/VisualStyleUnitSlider.js:
(WebInspector.VisualStyleUnitSlider.prototype.recalculateWidth):</pre>
