https://bugs.webkit.org/show_bug.cgi?id=82609 Patch by Allan Sandfeld Jensen <allan.jensen@nokia.com> on 2012-03-30 Reviewed by Kenneth Rohde Christiansen. Source/WebCore: Implement API for calculating the best zoomable area for a tap-to-zoom gesture. It picks the area with the largest intersection with the touch. In most cases this will be all areas fully containing the area, and returns the smallest inner-most of these. * page/EventHandler.cpp: (WebCore::EventHandler::bestZoomableAreaForTouchPoint): * page/EventHandler.h: * page/TouchAdjustment.cpp: (WebCore::TouchAdjustment::nodeIsZoomTarget): (WebCore::TouchAdjustment::appendZoomableSubtargets): (WebCore::TouchAdjustment::compileZoomableSubtargets): (WebCore::TouchAdjustment::areaOfIntersection): (WebCore::TouchAdjustment::findAreaWithLargestIntersection): (WebCore::findBestZoomableArea): * page/TouchAdjustment.h: * platform/graphics/IntSize.h: (WebCore::IntSize::area): Source/WebKit2: Add area to findZoomableAreaForPoint and use new TOUCH_ADJUSTMENT code-path to find the best zoomable area. * UIProcess/WebPageProxy.cpp: (WebKit::WebPageProxy::findZoomableAreaForPoint): * UIProcess/WebPageProxy.h: (WebPageProxy): * UIProcess/qt/QtWebPageEventHandler.cpp: (QtWebPageEventHandler::handleDoubleTapEvent): * WebProcess/WebPage/WebPage.cpp: (WebKit): (WebKit::WebPage::findZoomableAreaForPoint): * WebProcess/WebPage/WebPage.h: (WebPage): * WebProcess/WebPage/WebPage.messages.in: git-svn-id: http://svn.webkit.org/repository/webkit/trunk@112669 268f45cc-cd09-0410-ab3c-d52691b4dbfc
