The intention for sphinx is for detection of rendering errors inside
applications by simultaneously rendering on to the target device and on
an image surface and comparing the two. If it found a discrepancy, it
would then dump the trace that reproduces the error. (Then apply
delta-debugging to reduce that down to a minimal trace.)
