-/**
- * 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.
- *
- * <refsect2>
- * <title>Example launch line</title>
