feathered midbeam direction change

[Neil Thornock]

Hello list!

I've used the grow-direction property successfully in several cases.
But it only grows a beam in one direction.  I'd like to have a beam
grow toward the middle of the beamed group and then go the other
direction toward the end.  I'm ready to graduate from endless tweaking
to get this effect.

So my questions:

Is there a way to slope each individual beam manually (like just the
middle beam in 32nd notes)?  I can use the #'beaming property to get
all kinds of interesting beams, but I'd like to slope them independent
of each other.

Related, I suppose is:
How does the grow-direction property of beams *work*?  Can I access
that functionality manually?

Any other tips/hacks?

Thanks,
Neil
