Currently I am trying to simulate touch actions such as pinch, scroll, using the pointer events. I went through some of the marionette driver scripts: legacy_actions.py and gestures.py (even these are deprecated scripts) and found the algorithm for pinch method, followed the same algorithm while defining pinch method using pointer events.
Tested and observed that it is only selecting the content present between the two touch points, not zooming in/out. As I am a novice here, not clear whether I missed something or not. Please check and give your valuable comments.
