Nope - don't know how it works.  I've played with it, but did not know it would 
get the same exact thing I created.  Actually, perhaps I did not explain the 
one transition I created too well.  It is not a wipe like the shape wipe tool 
does.  It slides in the new image (or slides out the old) from the top or 
bottom, much like the transition that slides in or out from either side.  Based 
on what I have seen of the shape wipe (have not looked at the code yet mind 
you) I don't think it will do what I've done.

At any rate, before I go to far, I will work to understand the shapewipe better 
to be sure I don't reinvent the wheel.

Thanks,
Rob

So you don't know how ShapeWipe works?

ShapeWipe can do top-to-bottom wipes, checkerboard wipes, split from the 
center or into the center and whatnot. You only have to create a suitable 
gray-scale png. Look at the examples in $prefix/lib/cinelerra/shapewipe.

But, as Herman noted, it does have a few deficiencies. If you spend your time 
on wipes, then its best invested in improving the ShapeWipe plugin.
