Added Mouse based Zoom / Movement.

Browse source 
This patch uses the same code that lubomir used on the
old profile. It strangely didn't worked - most probably
because the scene has a fixed width() and height() of
100. the zoom works, and the movement works, but only
on the 100 first pixels of the profile.
