pinch to zoom and such

 From:  routb3d
I noticed that pinch zoom works in the viewports of both V2 and Beta V3 using a multitouch screen.. I'm not sure if this was intended or just happens to work but it would be useful for me to navigate the viewports via multitouch.. One thing is that the zoom operates to slow to be usable. I looked for a way to increase the sensitivity. zoom speed settings don't seem to have any effect on pinch zoom and I couldn't find anything on the ini file. Another thing is that it would be cool to set 1 and 2 finger touches to rotate (1 finger move), zoom (2 pinching) and pan (2 moving) like many 3d iPad apps. Any idea if this will be implemented or is already doable with some know how?
