Recently the panning test started failing. The reason is that the test environment now thinks that we have a touch environment instead of a mouse environment, probably because of the work on the debugging-in-the-browser work. This will move the test to a touch-based test.

Move from mouse events to touch events. Send both event types so that we won't fail in some situations. also mock requestAnimationFrame in the suiteSetup instead of setup. --- apps/homescreen/test/unit/grid_test.js | 49 ++++++++++++++++++++++++-------- 1 file changed, 37 insertions(+), 12 deletions(-) see also PR https://github.com/mozilla-b2g/gaia/pull/9478
