This is something that could be added.

Yes it is.

Could you expand on this. HOw would it work? I thought about this and
sort of just forgot about it because it was interfering w/ progress.

They are bound to visuals. You just have multiple cursors loaded into a visual
and you select the one you want to appear with the handle. The handle is only
to be used with one visual. All it does is specify which cursor to use. Say I
load cursor's A, B and C into visual V. I'have to be able to specify to visual
V that I want B to show.
A = ggiLoadCursor( V, A-data)
B = ggiLoadCursor( V, B-data)
C = ggiLoadCursor( V, C-data)
ggiSetCursor(V, B);
Of course if you have visual W,
ggiSetCursor(W, B);'
makes no sense because B was loaded into V not W. This would return an error.
Is this OK?

Nuff said.

Here you associate a handle with a visual. Would it make sense to use
this handle with another visual? I don't think so. This answers my question as
whether you think this is OK or not.
Thank you andy. I read the rest of your email and it made me feel more
comfortable with what I have done.
I really think we're on the same page. I really would like to hear about this
Hideifemulated business. You clearly have experience with the issue.
