-// touch-action applies to all elements with both width AND height properties.

We need to keep this logic (and comment) somewhere, the only real change is that
instead of "visible for touch action" it's more of a "supports touch action".  I
think leaving it on RenderObject (but renamed, eg "supportsTouchAction") is
probably best (although it could also be kept in EventHandler now I think).

-// According to the CSS Box Model Spec (http://dev.w3.org/csswg/css-box/#the-width-and-height-properties)
-// width applies to all elements but non-replaced inline elements, table rows, and row groups and
-// height applies to all elements but non-replaced inline elements, table columns, and column groups.
-bool RenderObject::visibleForTouchAction() const
-{
-    if (isInline() && !isReplaced())
-        return false;
-    if (isTableRow() || isRenderTableCol())
-        return false;
-
-    return true;
