Comment 2 for bug 1358327

This was tested on a nexus 4 device with qtdeclarative5-ubuntu-ui-toolkit-plugin: 1.1.1181+14.10.20140806-0ubuntu1

Another strange behaviour I'm seeing is the following:
- do a pinch gesture with 2 fingers: the output reports pinch.scale = 1
- while still leaving the 2 fingers on the glass, put down a third finger and do a pinch gesture with it: the output reports pinch.scale changing
