Hi Orson,
thanks for the great work!
When I've developed the Cairo backend, my idea was not only to use Cairo for printing but also as rendering engine for eeschema. For example compare GEDA gschem, they use there Cairo as well and the screen output looks in my opinion much better than eeschema (antialiasing / freetype fonts).
On my machine I've found Cairo not that slow for smaller boards - but I have an Intel Core I7. Perhaps it makes sense to hide the Cairo switch in another menu entry?
There is also a third backend that I've written last year, Orson has not included it - it uses wxDC. But wxDC has some drawbacks, it does not support transparency. Perhaps still useful as fallback solution ..
Bye,
Torsten

Doesn't it make more sense to fallback to the wxDC rendering? It's
known to work well except under certain conditions on OSX. You cannot
perform any editing other than using the P&S router so I'm not sure that
it's very useful as a fallback.
