Well you obviously did not recompile the latest gerbview with the patch that was
discussed Sunday night. 

20 seconds to update 12 gerver layers or so, on a super fast computer.

cairo is NOT the slowest.  Besides, current testing should speak louder than past
experiences.  I don't have an opinion yet on what is best for us.  I just KNOW it aint
what we are using.
