This is a meta bug for touch gestures that control the client application. Examples:
* Two-finger pan -> viewport panning
* Two-finger pinch/spread -> scaling/zooming
* Two-finger rotate -> open client menu (think F8-menu)
This bug encompass all ThinLinc clients (both native and web access).
See bug 7042 for sending touch events / gestures to the server. See bug 7111 for gestures that send emulated input.
