<h1>Example for composition modes</h1>
<p>
This example shows some of the more advanced composition modes supported by Qt.
</p>
<p>
The two most common forms of composition are <b>Source</b> and <b>SourceOver</b>.
<b>Source</b> is used to draw opaque objects onto a paint device. In this mode,
each pixel in the source replaces the corresponding pixel in the destination.
In <b>SourceOver</b> composition mode, the source object is transparent and is
drawn on top of the destination.
</p>
<p>
In addition to these standard modes, Qt defines the complete set of composition
modes as defined by Thomas Porter and Tom Duff. See the <tt>QPainter</tt> documentation
for details.
