You can't override this, we assume that if isTextField is true that
toRenderTextControlSingleLine is safe, but that's not true now.

Replaced with a new virtual RenderBox::isIntristicallyScrollable that scrollable
controls can use. This actually seems cleaner.

missing OVERRIDE on all of these

Done.

     virtual bool hasLineIfEmpty() const { return true; }
 };
