If canvas' render target is FramebufferObject, only the first drawImage() call
was successful, it could be fixed by adding beginNativePainting() and endNativePainting(),
but this could be unexpected behavior with OpenGL paint engine.

After calling transform related methods, the current path should be transformed with the same method but in reversal mode.
So that during painting, the painter will apply the CTM to this path again, otherwise path will be transformed twice.

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.

The QSG (SceneGraph) prefix is too generic for
Qt Quick(2)-specific classes.

All the classes and files in the declarative/items
directory have been renamed.

In particular, for classes that are currently public,
the renaming is as follows:

QSGView --> QQuickView
QSGCanvas --> QQuickCanvas
QSGItem --> QQuickItem
QSGPaintedItem --> QQuickPaintedItem

The header files have been renamed accordingly
(e.g. qsgview.h --> qquickview.h).

(This commit is in preparation of moving several files
to a separate library (QtQuick2).)

Don't add all subfolders to the includepath (from the
.pri files). There's no good reason to do that.

For headers (both public and private) that are in the
same folder as the file that includes them, prefer to use

 #include "foo.h"
 #include "bar_p.h"

For public headers that are outside the current folder
but have "unambiguous" names (e.g. qdeclarative prefix), use

 #include <foo.h>

For private headers that are outside the current folder, use

 #include <private/baz_p.h>

Also change

 #include <QtDeclarative/private/foo_p.h>

to

 #include <private/foo_p.h>

The header filenames already have a qdeclarative or qsg
prefix; there's no need to prefix by module name to
disambiguate.

Finally,

 #include "private/foo_p.h"

should be avoided. private/ is used for auto-generated
(forwarding) headers, which never reside in the current
(source) directory. Use angle brackets instead.
