Jon, i threw the capture along with a Form displayOn: Display in a
simple while loop and it's really slow. Do you think the FFI is the
responsible, and the performance hit could be avoided by converting it
to a plugin?

No, the performance hit is converting their pixel format into our pixel
format, which could also be fixed by switching this to a plugin and doing
that part in C.

If you end up doing a plugin for this, I'd be very interested in getting
it...

Later,
