+        WebKit2: add support for drag and drop
+        https://bugs.webkit.org/show_bug.cgi?id=52343
+        <rdar://problem/7660558>
+        
+        This patch contains the remaining work to support drag and drop on Mac.
+        I've added a PasteboardTypes class to encapsulate all the pasteboard formats
+        supported for drag and drop.
+        In this implementation we don't support the promised types, since I could not
+        find an efficient way to do this across processes.
+        The bulk of the patch consists in creating a shareable bitmap for the drag image,
+        pass its handle to the UI process and create a new NSImage from it to be given to
+        AppKit for dragging.
+        I've added the missing implementation of the methods in the drag client to hook
+        up the placement of the data in the pasteboard.

+        Crash in WebDatabaseManagerProxy::getDatabaseOrigins when called after the WebProcess has
+        died at least once
+        https://bugs.webkit.org/show_bug.cgi?id=52730
+
+        WebDatabaseManagerProxy::invalidate was setting m_webContext to 0, and invalidate gets
+        called in WebContext::processDidClose. However, m_webContext is only set in the
+        constructor, which is only called from the constructor of WebContext, so attempting to send
+        a message to any new WebProcess after the first one died was causing a null deref.
+
+        This patch moves setting m_webcontext into clearContext and clearContext is only called in
+        the WebContext destructor.
+
+        This patch also adds checks for a valid WebProcessProxy before attempting to send messages to
+        the WebProcessProxy so that if the WebProcess has died and has not been revived, it does not
+        attempt to dereference a null WebProcessProxy.
