It is still called for rectilinear non-pixel aligned boxes with a clip-mask.

The best benchmark is, of course, your own application. In order to help
us improve Cairo for your usage, you can record the calls made to Cairo by
your application using cairo-trace. We can then replay this trace and even
add it to our set of benchmarks and so tune Cairo for your application.

Have fun using Cairo, and please do send us a trace!
