Multitouch does not work on QNX

Multi-touch does not work on QNX, but it works without any issues on Linux.

On the QNX 7.1 target, multi-touch works well if you define in the mtouch.conf file that a maximum of 1 touchpoint is available. If you set this number higher, the touch is ignored and a message is displayed on the console:

qt.pointer.dispatch: skipping QEventPoint(id=1 ts=0 pos=0,0 scn=1,3162 gbl=1,3162 Stationary pressure=0.005 vel=0,0 press=-1,-3162 last=-1,-3162 Δ 1,3162) : no target window

If you use several fingers at once, you get more of these messages, and sometimes a point is painted on the widget. With 5 fingers, you will get up to 3 colors, all painted very much to the left side.
