<p>
The shapewipe element provides custom transitions on video streams
based on a grayscale bitmap. The state of the transition can be
controlled by the position property and an optional blended border
can be added by the border property.
</p>
<p>
Transition bitmaps can be downloaded from the
<a class="ulink" href="http://cinelerra.org/transitions.php" target="_top">Cinelerra transition</a>
page.
