System-wide multi-touch support on the HTC HD2 ?

It look like HTC did some fancy trick to make multi-touch available on a whole lot of Windows Mobile applications (that don’t natively support it) as seen in the video below showing some HTC HD2 pinch-zooming action in the Pocket Informant application. We’ve already seen the same thing in a previous video (here) where pinch-zooming was working in IGO Navigator. I’m guessing that it’s a frame buffer trick as it is similar to the way pinch-zooming is achieved in the video app of the HD2.

Longer video with more apps (Opera Mobile ,mail etc..):

Looks like HTC’s mail applications uses Opera Mobile‘s engine to render the mail and enable pinch-zooming.
