#mouseWheel: knows too much
Hello
In latest builds of Pharo 4 (in last 2 months probably), there has been a
change in settings of mouse wheel event creation.
In HandMorph #generateKeyboardEvent:
In Pharo 3 there is MouseWheelEvent created by calling
MouseWheelEvent new
setType: #mouseWheel
position: lastMouseEvent
