Wayland touch event patch

Hello,

Attached is a small patch which enables multitouch events on Wayland.

Please review and release the changes as per your policy.

Touch coordinate are supposed to be normalized within [0, 1] in the window (for direct finger touches), or normalized within [0, 1] in the touch device (for indirect touches, e.g. trackpads).

The X11 backend does pixel coordinates right now I think, but that's a bug. All of the other backends do proper normalized coordinates.

Moritz, can you take care of normalizing the coordinates and testing your patch?

Thanks!
