That is great news! I believe that VG can simplify the UI and improve 
the looks and experience for any kind of apps, like it does for DrGeo.

In November 2022, I integrated UnicodeString. Since them, anywhere you 
may expect an instance of String, you may instead get an instance of 
UnicodeString. This hasn't brought much trouble, as they are 
polymorphic. But a few tweaks here and there were needed. Last commit to 
FFI.pck.st is from Jan 6 and it was specifically for this.

On my Intel Mac, using an updated Cuis, and loading `Feature require: 
'Tests-FFI'`, all the FFI test pass. Do they pass on your Apple Silicon Mac?

I believe we can. Not too long ago, before Apple dropped support for 
OpenCL, I used it extensively, and I believe it was a dylib. Nowadays, 
I'm not using FFI much.

Can you help me reproduce what you are doing on my Mac? I'd like to see 
it running on a Cuis from the date it did work from you, and also 
reproduce your updated setup to see the failure.

Do you get a debugger? Error messages? Something on the Transcript or 
StdIO (in Terminal)?

If I can reproduce your setup and the problems you see, I'm sure we'll 
fix them.
