Fixed #23. QtD_QObjectEntity is not created dynamically for shell classes any more. Class initialization is now performed by static constructors. When wrapping QObjects returned from functions, their run-time types are now taken into account. QObjects are allocated on GC heap, a doubly-linked list is used to prevent them from been collected (arguably a better solution than allocating on C heap and adding GC ranges) Minor changes (including unnecessary).

<h2>Vector deformation</h2>
</center>

<p>This demo shows how to use advanced vector techniques to draw text 
using a <code>QPainterPath</code>.</p>

<p>We define a vector deformation field in the shape of a lens and apply
this to all points in a path. This means that what is rendered on
screen is not pixel manipulation, but modified vector representations of
the glyphs themselves. This is visible from the high quality of the
antialiased edges for the deformed glyphs.</p>

<p>To get a fairly complex path we allow the user to type in text and
convert the text to paths. This is done using the
<code>QPainterPath::addText()</code> function.</p>

<p>The lens is drawn using a single call to <code>drawEllipse()</code>, using
a <code>QRadialGradient</code> to fill it with a specialized color table,
giving the effect of the Sun's reflection and a drop shadow. The lens
is cached as a pixmap for better performance.</p>
