Cairo is a bit slower unfortunately. I've found this from the work I've
done to try and use it in gschem, and Tomaz found the same before me.

When I get chance, I'll take a look at gerbv, and see if there is
anything obvious its doing wrong.

Does cairo now support your boxen Ok Dan? (I remember 8 bit visuals were
a problem before.)

I am not on that list, no. Its great to hear gerbv is coming along well
though.. I'll have to checkout the CVS version!

Yes, thats what I meant (joining different designs to from one big
panel). And they won't all be authored using PCB - which makes it
harder.
