Work on tablet

Hi,

I fixed some bugs to work ros3djs library on tablet successfully.
In particular there is a difference in how to get positions between TouchEvent and MouseEvent, so I mainly wrote the glue codes.

Now, users can
1: rotate (1 finger), pinch in/out (2 fingers), swipe (3 finger).
2: move interactive markers.

Anything else:
Cylinder markers use the wrong order in scale (The axis rotation was not considered !) -> I fixed.
