Merge branch '4.7' of scm.dev.nokia.troll.no:qt/qt-qml into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/qt-qml: (112 commits) Verbose unexpected errors. One url for an *unqualilfied* import is not special. Fix test failures Optimization: Don't unnecessarily run VMEStack element constructors Optimization: Reduce unnecessary QObject allocations Reset QDeclarativeDeclarativeData::outerContext when the context is removed Simplify QDeclarativeComponent::creationContext() logic Optimization: Use id notifier for QtScript bindings Optimization: Combine QDeclarativeDeclarativeData and QObject allocations Fixes for the module import Fix documentation add alan's tic-tac-toe AI Remove test in .pro file also Remove unneeded #include and add needed header to .pri Add easing changes to QmlChanges.txt Update more animation on property value source docs. Doc fixes. QmlChanges.txt cleanup. Remove WorkerListModel and integrate its functionality into ListModel. Split post alpha API changes into a separate section. ...

 =============================================================================
+The changes below are pre Qt 4.7.0 beta
+
+PathView: offset property now uses range 0-1.0 rather than 0-100
+ListView, GridView::positionViewAtIndex() gained a 'mode' parameter
+Removed Qt.playSound (replaced by SoundEffect element)
+Removed Qt.closestAngle (use RotationAnimation instead)
+Removed NumberFormatter
+Removed DateTimeFormatter (use Qt.formatDateTime() instead)
+Using WebView now requires "import org.webkit 1.0"
+Using Particles now requires "import Qt.labs.particles 1.0"
+AnchorAnimation must now be used to animate anchor changes (and not NumberAnimation)
+
+C++ API
+-------
+QDeclarativeContext::addDefaultObject() has been replaced with
+QDeclarativeContext::setContextObject()
+
+Behavior and Animation syntax
+-----------------------------
+Previously animations and behaviors could be "assigned" to properties like this:
+    Item { x: Behavior {}; y: NumberAnimation {} }
+To make it more obvious that these are not regular value assignments a new "on"
+syntax has been introduced:
+    Item { Behavior on x {}; NumberAnimation on y {} }
+Only the syntax has changed, the behavior is identical.

-- root() -> rootObject(),  returns QGraphicsObject rather than QmlGraphicsItem

-QML_REGISTER_... registration macros, which must be called explicitly. C++ API users
-should also consider using the QmlExtensionPlugin (previously named QmlModulePlugin)
-as a cleaner mechanism for publishing libraries of QML types, or the upcoming 
-application plugin features of the qmlviewer / qmlruntime / qml.

 PropertyAnimation
 ------------------
 matchProperties and matchTargets have been renamed back to properties and targets.
 The semantics are explained in the PropertyAnimation::properties documentation
 and the animation overview documentation.
 
-Behavior and Animation syntax
------------------------------
+Easing curves and their parameters are now specified via dot properties:
+* easing.type : enum
+* easing.amplitude : real
+* easing.overshoot : real
+* easing.period : real
+For example:
+PropertyAnimation { properties: "y"; easing.type: "InOutElastic"; easing.amplitude: 2.0; easing.period: 1.5 }

+\enum QDeclarativeEngine::ObjectOwnership
+
+Ownership controls whether or not QML automatically destroys the QObject when the object 
+is garbage collected by the JavaScript engine.  The two ownership options are:
+
+\list
+\o CppOwnership - The object is owned by C++ code, and will never be deleted by QML.  The
+JavaScript destroy() method cannot be used on objects with CppOwnership.  This option
+is similar to QScriptEngine::QtOwnership.
+
+\o JavaScriptOwnership - The object is owned by JavaScript.  When the object is returned to QML
+as the return value of a method call or property access, QML will delete the object if there
+are no remaining JavaScript references to it and it has no QObject::parent().  This option
+is similar to QScriptEngine::ScriptOwnership.
+\endlist
+
+Generally an application doesn't need to set an object's ownership explicitly.  QML uses
+a heuristic to set the default object ownership.  By default, an object that is created by
+QML has JavaScriptOwnership.  The exception to this are the root objects created by calling
+QDeclarativeCompnent::create() or QDeclarativeComponent::beginCreate() which have 
+CppOwnership by default.  The ownership of these root-level objects is considered to have
+been transfered to the C++ caller.
+
+Objects not-created by QML have CppOwnership by default.  The exception to this is objects
+returned from a C++ method call.  The ownership of these objects is passed to JavaScript.
+
+Calling setObjectOwnership() overrides the default ownership heuristic used by QML.

-    \qmlclass WorkerListModel QDeclarativeWorkerListModel
-    \brief The WorkerListModel element provides a threaded list model.
-
-    Use WorkerListModel together with WorkerScript to define a list model 
-    that is controlled by a separate thread. This is useful if list modification 
-    operations are synchronous and take some time: using WorkerListModel
-    moves these operations to a different thread and avoids blocking of the
-    main GUI thread.
-
-    The thread that creates the WorkerListModel can modify the model for any
-    initial set-up requirements. However, once the model has been modified by
-    the associated WorkerScript, the model can only be modified by that worker
-    script and becomes read-only to all other threads.
-    
-    Here is an example application that uses WorkerScript to append the
-    current time to a WorkerListModel:
-
-    \snippet examples/declarative/workerlistmodel/timedisplay.qml 0
-
-    The included file, \tt dataloader.js, looks like this:
-
-    \snippet examples/declarative/workerlistmodel/dataloader.js 0
-
-    The application's \tt Timer object periodically sends a message to the
-    worker script by calling \tt WorkerScript::sendMessage(). When this message
-    is received, \tt WorkerScript.onMessage() is invoked in
-    \tt dataloader.js, which appends the current time to the worker list
-    model.
-
-    Note that unlike ListModel, WorkerListModel does not have \tt move() and
-    \tt setProperty() methods.

     \brief The AnchorChanges element allows you to change the anchors of an item in a state.
 
-    AnchorChanges will 'inject' \c x, \c y, \c width, and \c height changes into the transition,
-    so you can animate them as you would normally changes to these properties:
+    In the following example we change the top and bottom anchors of an item:
+    \qml
+    AnchorChanges {
+        target: content; top: window.top; bottom: window.bottom
+    }
+    \endqml
+
+    AnchorChanges can be animated using AnchorAnimation.
     \qml
     //animate our anchor changes
-    NumberAnimation { targets: content; properties: "x,y,width,height" }
+    AnchorAnimation {}
     \endqml
 
     For more information on anchors see \l {anchor-layout}{Anchor Layouts}.
