--- Comment #6 from Chris Wilson <chris at chris-wilson.co.uk> ---
The really interesting aspect of the trace is the where the drawing is nested
10s of levels deep (>50) with all the results being kept around in a stack
until they get masked onto the output. It's certainly the first time I've seen
that pattern in a trace, and it may indeed be the right approach for you, but
it looks inefficient.

Also you have to be aware that you will be limited by driver quality when using
cairo-xlib, which is likely to be a contributing factor as well as the hw
differences for comparing SNB to the Nexus7.
