/**
* SECTION:element-shapewipe
*
* 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.
*
* Transition bitmaps can be downloaded from the
* <ulink url="http://cinelerra.org/transitions.php">Cinelerra transition</ulink>
* page.
