This is a follow-up of Webkit patch for issue 24187 -- RTL: tooltip does not get its directionality from its element's directionality. In the above patch, Webkit passed in both tooltip text and its element directionality to client. To make Chromium build OK after the signature change in Webkit, an overloaded virtual function ChromeClientChromium::setToolTip(const String&, TextDirection) was introduced. Now since Chrome changed its signature in its Webkit glue layer (ChromeClientImpl::setToolTip()), the overloaded ChromeClientChromium::setToolTip() is no longer needed.
