"Alpha determines radius" option makes that track disappear in the<br>
Compositor leaving a black background. It is as if this option took<br>
the black of the first track (which is 100% transparency) and<br>
transformed it into the color black (0, 0, 0), losing the transparency<br>
data and hiding the underlying colored track. The same is achieved<br>
using a gradient.<br>

Maybe the best thing is to hide the option (without needing to remove<br>
it from the source code) so that it is not available.<br>
