User Story:
As a user when I am surfing the web, the Firefox OS browser should feel responsive/snappy when I pinch to zoom in/out.

Benchmark stats to define "responsive/snappy": 
*50 ms lag when user pinches to zoom in/out
*Content repainting should be >=55fps

Acceptance criteria:
*User can consistently zoom in/out with a lag time of <=50ms
*The browser content repaints at >=55fps

I think we need to find a way of automating testing this, similar to robocop on Android. Maybe eideticker would be enough?

Anyway, sprint-ready I suppose. Locally, using the tiled backend on a Keon, zooming feels smooth to me.

Not sure if it's feasible to do perf testing manually.

This bug depends on an automated testing capability of the pinch zoom feature.  Eiditicker is still a work in progress and will give us this capability when finished.
