pcb 20150206-0ppa0~utopic (from
https://launchpad.net/~mehanik/+archive/ubuntu/geda-unstable - source is
https://launchpad.net/~mehanik/+archive/ubuntu/geda-unstable/+files/pcb_20150206.orig.tar.gz)

just tried with a 902x600 image: I see no diagonal skew, but the image
is stretched to fit the board (which is probably intentional and makes
sense for this application)
