[WK2] Minimum layout width auto-sizing should use FrameView::enableAutoSizeMode so that it can shrink the viewport https://bugs.webkit.org/show_bug.cgi?id=107200 <rdar://problem/12849029> Reviewed by Simon Fraser. Make use of FrameView's auto-size mode to allow WKView's computed intrinsic content size to shrink below the current viewport size. * UIProcess/WebPageProxy.cpp: (WebKit::WebPageProxy::setMinimumLayoutWidth): Forward minimumLayoutWidth changes to WebPage. * UIProcess/mac/TiledCoreAnimationDrawingAreaProxy.mm: (WebKit::TiledCoreAnimationDrawingAreaProxy::sendUpdateGeometry): Remove minimumLayoutWidth argument on updateGeometry. * WebProcess/WebCoreSupport/WebFrameLoaderClient.cpp: (WebKit::WebFrameLoaderClient::transitionToCommittedForNewPage): Enable auto-size mode on the new FrameView if needed. * WebProcess/WebPage/DrawingArea.h: (WebKit::DrawingArea::updateGeometry): Remove minimumLayoutWidth argument. * WebProcess/WebPage/DrawingArea.messages.in: Remove minimumLayoutWidth argument on updateGeometry. * WebProcess/WebPage/WebPage.cpp: (WebKit::WebPage::WebPage): Initialize m_minimumLayoutWidth to 0. (WebKit::WebPage::setMinimumLayoutWidth): Keep track of minimumLayoutWidth on WebPage. Update auto-sizing state if needed. * WebProcess/WebPage/WebPage.h: (WebKit::WebPage::minimumLayoutWidth): * WebProcess/WebPage/WebPage.messages.in: Add SetMinimumLayoutWidth. * WebProcess/WebPage/mac/TiledCoreAnimationDrawingArea.h: (TiledCoreAnimationDrawingArea): Remove storage for m_minimumLayoutWidth. We can get it from WebPage instead. * WebProcess/WebPage/mac/TiledCoreAnimationDrawingArea.mm: (WebKit::TiledCoreAnimationDrawingArea::TiledCoreAnimationDrawingArea): (WebKit::TiledCoreAnimationDrawingArea::mainFrameContentSizeChanged): Grab minimumLayoutWidth from WebPage. (WebKit::TiledCoreAnimationDrawingArea::updateGeometry): Don't setSize() if auto-sizing is enabled; FrameView will do the right thing. * WebCore.exp.in: Export FrameView::enableAutoSize(...). git-svn-id: http://svn.webkit.org/repository/webkit/trunk@140087 268f45cc-cd09-0410-ab3c-d52691b4dbfc
