the viewport is hard to use with touchpad

[vladimir-kraus]

I did not manage to find a way to use the vierport with touchpad. It only allows zooming and even zooming is so fast it cannot be controlled. Please implement viewport panning with touchpad.

Thanks for the feedback.

So far Slate has only really been properly tested with mouse and e.g. MackBook trackpad. Some work will need need to be done to make it touch-friendly.
