I'm not sure about the "always" part, but here's an updated patch for
compareFB at least.

Not sure if I understand why it couldn't be overridden by passing

Suggested patch. It does the following:
- CUT block size changed to 64 pixels. This size in most cases has a
CPU usage similar to 256 pixels, but a coverage more similar to 16
pixels.
- Default compression level changed to 2. Based on your numbers, this
seems to get us most of the compressi

Well, then, what are you considering to be appropriate WAN settings?

Nice work!
If Cendio wants the CUT always enabled for their product, then that is
