+<h1>Demo for composition modes</h1>
+
+<p>
+  This demo 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.
