Say hello to QtQuick module
This change moves the QtQuick 2 types and C++ API (including SceneGraph) to a new module (AKA library), QtQuick. 99% of this change is moving files from src/declarative to src/quick, and from tests/auto/declarative to tests/auto/qtquick2. The loading of QtQuick 2 ("import QtQuick 2.0") is now delegated to a plugin, src/imports/qtquick2, just like it's done for QtQuick 1. All tools, examples, and tests that use QtQuick C++ API have gotten "QT += quick" or "QT += quick-private" added to their .pro file. A few additional internal QtDeclarative classes had to be exported (via Q_DECLARATIVE_PRIVATE_EXPORT) since they're needed by the QtQuick 2 implementation. The old header locations (e.g. QtDeclarative/qquickitem.h) will still be supported for some time, but will produce compile-time warnings. (To avoid the QtQuick implementation using the compatibility headers (since QtDeclarative's includepath comes first), a few include statements were modified, e.g. from "#include <qsgnode.h>" to "#include <QtQuick/qsgnode.h>".) There's a change in qtbase that automatically adds QtQuick to the module list if QtDeclarative is used. Together with the compatibility headers, this should help reduce the migration pain for existing projects. In theory, simply getting an existing QtDeclarative-based project to compile and link shouldn't require any changes for now -- but porting to the new scheme is of course recommended, and will eventually become mandatory.

- \qmlclass Drag QQuickDrag
- \inqmlmodule QtQuick 2
- \brief The Drag attached property provides drag and drop events for moved Items.
-
- Using the Drag attached property any Item can made a source of drag and drop
- events within a scene.
-
- When a drag is \l active on an item any change in that items position will
- generate a drag events that will be sent to any DropArea that intersects
- the with new position of the item. Other items which implement drag and
- drop event handlers can also receive these events.
-
- The following snippet shows how an item can be dragged with a MouseArea.
- However, dragging is not limited to mouse drags, anything that can move an item
- can generate drag events, this can include touch events, animations and bindings.
-
- \snippet doc/src/snippets/declarative/drag.qml 0
-
- A drag can be terminated either by canceling it with Drag.cancel() or setting
- Drag.active to false, or it can be terminated with a drop event by calling
- Drag.drop(). If the drop event is accepted Drag.drop() will return the
- \l {supportedActions}{drop action} chosen by the recipient of the event,
- otherwise it will return Qt.IgnoreAction.
