The PathText would always translate to y=0, regardless of what y
was set to. We should obviously get the y coordinate of the shape
*before* translating it into position to find the distance from
the baseline.
This change also updates the example, which had not been updated
to the changed origin of the PathText, and it adds a Lancelot test
for keeping track of the PathText shape rendering.

For text rendering in Qt Quick, we currently have the limitation
that when rendering text at such a large size that the distance
fields start showing artifacts, the only option is to use
NativeRendering, which will look nice, but which will use a lot
of texture memory for the glyph cache, since it will actually
cache the glyphs at the requested size.
A suggested approach would be to fall back to using triangulated
paths when the font gets large enough, but the work on this was
never completed.
It turns out that we can get this now, basically for free, since
we already support rendering arbitrary QPainterPaths using
Qt Quick Shapes. The only thing missing is the ability to add
the path of a given text to the shape. This patch fills in that
gap.
Note that this is currently not supported by nvidia renderer.
[ChangeLog][QtQuick] Added PathText path element which can be
used together with Qt Quick Shapes to get text rendering that
does not cache glyphs in a texture, but triangulates the
outlines of the glyphs instead.

We don't want to encourage Qt.createQmlObject(). It's the equivalent of
eval() in JavaScript.
This has the added benefit that the shapes actually react to changes in
the parameters now. Before, once a shape was drawn, it didn't get
updated when you manipulated the line width or fill controls.

This isn't an improvement in behvior, it just shows that a Shape can
be used as a mask on some other Item. But Shape.containsMode is still
important so that when the outer Rectangle's contains() calls
Shape.contains(), the latter will do the right thing.

QQuickItem::contains() only checks the Item's bounding box by default.
In the case of Shapes, that can be comically imprecise, but it's fast.
So we add a containsMode property to control whether we will do that
(the default) or actually check each of the QPainterPaths within to
see whether they contain the point (FillContains).
FillContains could be optimized later: use QRegion perhaps, or download
the rendered texture from the GPU and test whether the pixel at the
point is transparent. It may also be appropriate to add a StrokeContains
option.
The main motivation is to detect mouse (or touch) interaction within
a shaped area. QQuickSinglePointHandler::wantsEventPoint() already
checks whether its parent Item contains the event point. So if a
Shape has a TapHandler for example, it will respond only within the
visible bounds of the Shape rather than within the entire rectangular
bounding box as long as containsMode is set to FillContains.
Examples quick/shapes/content/tapableTriangle.qml and tiger.qml
are modified to react when a press occurs inside, and the former
is fixed to be able to run standalone via the qml runtime. The
latter has an offset issue when run standalone but is OK within
the shape gallery example.
As a drive-by optimization, QQuickShapePrivate's variables are
re-ordered by type so that the compiler can place the bools and
enums into bitfields; and to facilitate reordering, the
initialization is done C++11-style, in the header.
[ChangeLog][QtQuick][Shape] A containsMode property is added.
If it is set to FillContains, then Shape.contains() returns true
only within the visible bounds, so its Pointer Handlers also respond
only within those bounds.

The own list property must be kept. However, we can reuse
QQuickItemPrivate's data accessors in order to start supporting
code like:
Shape {
..
ShapePath { ... }
ShapePath { ... }
Rectangle { ... }
Image { ... }
// any other visual type
// or non-visual:
Timer { ... }
}

Thus application code becomes:
ShapePath {

fillGradient: LinearGradient {
...
GradientStop { ... }
}
}
which is even more clean and readable. The duplication for stops is
now avoided.
