Mac OS X, Intuos tablet fix

Touch input events map nicely to trackpad input now.
However, I noticed the event values are a factor 10 scaled larger compared
to other touch delta's. Makes using touch input on the tablet not so nice.

I found a hack to detect Wacom events, but if it works for more devices?

Anyway - for me the Wacom works perfectly smooth for view manipulations now.
