<h3>Log Message</h3>
<pre>All scrolling height/width values should be integral rounded.
https://bugs.webkit.org/show_bug.cgi?id=157687
Reviewed by Simon Fraser.
Both clientHeight(Width) and scrollHeight(width) need to be explicitly integral
rounded in order to ensure that scrollable content is computed properly.
This will evolve into subpixel snapping once we apply subpixel arithmetics on scrolling.

+ All scrolling height/width values should be integral rounded.
+ https://bugs.webkit.org/show_bug.cgi?id=157687
+
+ Reviewed by Simon Fraser.
+
+ Both clientHeight(Width) and scrollHeight(width) need to be explicitly integral
+ rounded in order to ensure that scrollable content is computed properly.
+ This will evolve into subpixel snapping once we apply subpixel arithmetics on scrolling.
+
+ Not testable.
